Scott McCall x male reader

Ficlet

Scott has always had a special part in my heart ever since I watched Teen Wolf years ago. You are so right about the lack of bottom Scott content, so I hope this helps scratch that itch a little bit.

Reader is a kanima-wolf combo, like Jackson, cuz I love the kanima plot. did someone say tailplay? cuz theres tailplay.

I had a lot of fun writing this ngl, hope you guys enjoy.

Scotts claws dug deep groves into the floor, a high-pitched whine leaving him as the powerful flexible muscle of your tail curled around his middle, dragging him closer to where you were crouched near the shadowed corner of the room.

The day had been spent high strung on your part, as Scott had seemed to make it his mission to tease you. From sultry looks as he bit his lip, or the way he would push his scent at you specifically to leave you agitated. He seemed to take it as a win when he caught your tongue flicking out between your lips, tasting the air as your leftover reptilian instincts demanded of you.

You had been a kanima when you were bitten, around the same time as Jackson. It stemmed from similar issues to Jackson, something deep and emotional that left you feeling like you weren’t in control of yourself. You had to live up to very high expectations set by your parents, who were very strict about everything you did, also making it impossible for you to accept your sexuality at the time.

But with the help of the pack, you came to accept yourself, and like Jackson, you turned into something more of a hybrid, a mixture of a kanima and a werewolf. Unlike Jackson, you always fell more back onto your reptilian urges than the wolf urges, which was why you were now hissing softly as your slitted eyes bore into the naked back of your lover as you dragged him towards you.

With a flick of your tongue, you could taste the strong arousal in the bedroom, Scott’s bedroom, the faint scent of precum reaching your heightened senses. With a rumbled hiss, you wrench down the pajama pants Scott had been wearing, striking your lightly scaled hand across his naked ass. “You’re so dirty Scott, you were waiting for me, huh?” you hiss, squinting up at him as he looks at you over his shoulder, a slight squint to his eyes that told you that your guess had been correct.

Your tail released his middle as he laid out flat across the floor, lifting his hips just enough for you to pull his pants all the way down and off without tearing them. A whimper left him as your claws ran across his thick thighs, groping the muscle underneath with an appreciative hiss. “So needy” you mumble, digging your thumbs into the dimples of his back, making him keen breathlessly.

Your pupils shrank into slits as you watched how his muscles tensed, his back arching so beautifully as Scott shuffled his knees apart, trying to fit your torso between them as you scraped your sharp teeth across his lower back. The threat of your venom had only ever served to arouse him further, the possibility of being completely paralyzed sending a bolt of thrill and lust through your lover’s entire body.

It was something you had only experimented with once or twice, when you both had felt a little more in control of your more beastly half. But as of now, your tail lashed out, knocking something random off a shelf in the background. Scotts softly glowing eyes met yours as he looked back at you again, audibly gulping and whining softly, almost beckoning you to touch him more.

Spreading his cheeks apart, your tongue started to roll out of your mouth, ready to slither inside him to spread him open the way you knew he loved the most, until you saw the familiar shiny sheen across his pucker. “Did you prep yourself Scott?” you asked with a slight lisp, your longer than humanly possible tongue still hanging out of your mouth.

Instead of answering, Scott simply blushed and buried his head into his folded arms, his knees shuffling to allow him to lift his hips farther, giving you all the answer you needed. Instead of teasing him further, you crawled up his body, letting your torso drag across his back until your chest was pressed against his back, chin hooked on his shoulder.

Your tail coiled around one of his thighs, far up enough that part of your warm scales brushed around his pouch, making him twitch and moan, eyes fluttering shut at the feeling of smooth scales against his skin. “You’ve always been such a freak Scott, never imagined you’d be so turned on by scales” you snicker, tone teasing but also thick with want, half hissed as your tongue felt too long for your mouth.

“Maybe I should just fuck you with my tail instead, what do you say?” you murmur into his ear, the tip of your tail just barely pressing against his slick pucker, making Scotts hips flex as his jaw drops in a soundless moan. You knew it was a fantasy of his, you bet hed even let him fuck him when you were still just a kanima, ruled by a master and mind not your own.

You had seen his search history, you knew the kind of stuff he was into, and if that just so happened to always involve a lot of stuff that was similar to your anatomy? Who would have to know but you, Scott, and God.

The tip of your tail just barely pressed inside, your tongue reptilian tongue pressing against his pulse point as Scott moaned, head falling to the side to give you as much access to his throat as possible. It was an extremely submissive pose for a true alpha like Scott, but it always served to make you feel a deep feral rush, to somehow get someone like Scott under you and writhing.

But before your tail could breach the loosened ring of his hole, you pulled it back, doing your best to ignore the whined out “no, no, please” from Scott. Instead, you reached down and undid your belt, quickly releasing your hard length and letting it rest between the globes of his ass, rolling your hips against his to let him feel it.

“Next time, my cute little alpha” you tease, your sharp teeth scraping hard enough against his shoulder to make blood bead up at the bites, but they quickly healed over, only giving you a slight taste. “Please, please, please” Scott whimpered, sounding almost near tears. Its seems you hadn’t been the only one worked up all day, as Scott almost outright panted for your touch, your cock, your tail, anything.

You swore you could see him drooling as you finally press inside him, his hips shoving back against yours hard enough, that if you weren’t holding him still, he would have impaled himself onto your dick almost immediately. A slight warning hiss-growl left you, as if warning him to stay still. A rumble left him in response, his inner alpha seemingly feeling disrespected by your display, even as Scott arched and moaned for more.

Scott was only given a moment to adjust, just how he liked it, before you started moving your hips. A clawed slightly scaled hand was placed between his shoulder blades, shoving his face harder against the floor as your hips struck against his own, his noises rising in volume and neediness.

Scotts claws ached as they dug into the floor, his fangs flashing as his jaw dropped, open mouthed gasps and moans leaving him as the noises were punched out of him, tongue almost hanging out as drool ran down his chin.

As you struck his prostate, he almost wailed, but before that noise could leave him, the tip of your tail was shoved between his teeth, pressing down against his tongue, and tickling the back of Scotts throat, only making his eyes roll back as he groaned.

Your noises were akin to chuffing as your hips slammed against his, claws digging into Scotts back and hip hard enough to draw blood as venom filled drool dripping from your mouth and down into the divot of his spine. Scott gagged as your tail shoved deeper into his mouth, part of it pushing down his throat as he moaned and sucked on it like it was your cock, spit and drool running down his chin and creating a puddle under him.

There was no way for him to beg with words for you to go faster, but Scott was able to wrench one of his hands from the floor, reaching back to hold onto your hip, urging you to go faster, deeper, harder. So, with a deep hissed growl, you did, striking his sensitive prostate with the precision of an expert, making him keen around the scaley meat of your tail.

You weren’t even sure when Scott came, his cock squirting across the floor in thick white spurts, his eyes rolling back as the euphoria crashed through his body and making him tighten around you. But you were too consumed by your own pleasure, hisses and growls leaving you as you kept pounding into him, taking great pleasure in the wet slick noise of your hips meeting his ass, and how it left him moaning and crying out for more.

When you finally reached your end, you crushed your hips against his, your sharp teeth digging into his shoulder as you came, cumming deep inside him in the way you knew he loved as it made him feel so full of you. Your tail withdrew from his mouth with a wet sputter, strings of drool hanging from the deep green scaled to his pink wet mouth, a noise so high pitched you barely heard it as he came a second time.

Purring filled the room as you held Scott, grinding lazily into him as you milked your mutual orgasms as much as possible, before Scott finally slumped, completely limp and panting. You would think you had injected him with your venom with how limp he went, but in reality, it was just the post orgasm bliss.

With a soft kiss pressed against the already healing bite, you carefully pull you and get Scott to his feet, shuffling him into the bathroom to get him cleaned up, maybe even give him a nice warm shower so you two can be washed up. After getting him dressed in a new part of pajama pants, you tuck him into bed, expertly cleaning up the mess of blood, drool, and other bodily fluids left on the floor. You’ll have to find a way to fix the groves you guys left in the floor, but that was for later.

When all was said and done, you could finally allow yourself to crawl into bed with Scott, the scales on your skin receding for the most part, claws and sharp teeth disappearing to where they came from, and your eyes returning to your usual ones. The only thing that stayed was your tail, which curled around Scott in a loving embrace as you pulled him close to your chest.

Scott let out a soft huff, snuffling closer to your neck before he went limp once more, almost laying completely on top of you, basking in your presence and scent as he felt safe enough to be completely vulnerable, sleep quickly rushing up on him. You didn’t feel tired, so like usual, you laid back and held Scott as he snored softly, one hand rubbing up and down his back as you scrolled your phone with the other. His body heat always left you feeling sluggish afterwards, some kind of reptile reaction, but it made you feel safer to watch over him as he slept, so that it what you did, until Scott was ready to wake up again.

teen wolf meme: [5/6] creatures -> kanimas

Like the wolf, the Kanima is a social creature. But, where the wolf seeks a pack, the Kanima seeks a friend. A friend. What does that mean? Maybe it's lonely? ...Like a teenager.

[edison-khc]

i have a healthy relationship with the 2011-2017 show teen wolf, most definitely

anyway here is jackson whittemore as a tarot card!

i chose the devil because his character is defined by his lack of fufillment and his desire to succeed (also hes very materialistic which also works)

i also gave him some snapdragons and foxgloves as dressing for the piece because they symbolize deception but also a will to thrive and toxicity and insecurity respectively. (im paraphrasing but you get me)

[74204-133]

Who Sude i make a vore Story of

This time the Story will only Happen ween you give me ideas for the charater If Not i wont give you tham you Tell me in the Tumblr Chat OK DO NOT REBLOGG WIF YOUR IDEA IT SUDE BE A SURPRISE (If you want i give you my discord Name so we can Chat there)

HOW have I NEVER considered post-nogitsune Stiles and Jackson bonding before I AM A FOOL.

The nogitsune and the kanima taking their autonomy from them, using them to hurt the people they care about.

I love the Stiles and Jackson friendship. I crave it. How have I been so blind and not seen this potential. I am an idiot.

I mean, I know why I haven't seen it until now. My highest priorities in fic reading are 1. Sterek, 2. Erica and Boyd are alive, and 3. Jackson doesn't leave. And most fics including all of these take place within the space between s2 and s3, or are explicit rewrites of 3A.

Though, as a fan of Kira and lover of the nogitsune plotline and consequent angst of it, I generally need more fics catering to my specific interests by including 1.)-3.) and going up to at least 3B.

Someone send recs. Please.

Gather round teen wolf fans I need you. So when Jackson turned into a proper werewolf, post-kanima, his eyes were blue, implying that he was responsible for the deaths he caused as the kanima (personally I hate this because he was literally being controlled by Matt and Gerard but okay).

With that in mind:

There are compelling arguments to both options, I'm going to drop the simplest ones here.

Blue, in that Stiles feels responsible for the carnage caused by the nogitsune as he was the one who "let it in", thereby taking on the blame for the deaths it caused, regardless of his own agency in the killings. (This aligns with Theo's "remorse" theory later in canon, implying the colour of a wolf's eyes depends on their personal feelings of guilt/remorse.)

Yellow, in that the nogitsune possessed Stiles, he wasn't in control of his own actions and thereby he is not the one at fault for what happened, meaning that the deaths caused by the nogitsune are not his to bear. (This aligns more with what we knew of canon prior, which is that the colour changes if a wolf knowingly takes an innocent life.)

Reblog if you vote, please, so this can reach as many teen wolf fans as possible. Also if you have alternate theories/explanations/thoughts on this feel free to add them in your responses, I'm really eager to see what you guys all think.

[simpingcorner]

Jackson being completely and utterly clueless the entire time in Teen Wolf the Movie is honestly a mood.

Also the lack of mentions of Kira Yukimura and her Nogitsune is very upsetting.

[fairytalegumiho]

Stop saying Derek is a villain in Season 2.

He is not. Why would you say that? The actual antagonists in season 2 are Matt, Gerard and his lackeys, Kanima not Derek.

Just because he became a villain for trying to kill Lydia then Allison should also be a villain for trying to kill Derek and his whole pack.

Derek told Boyd, Erica, Isaac everything that they needed to know at that point. He gave them a new life. He only wanted to kill Lydia because he thought she was a kanima and he didn't want the normal people to die. But we don't even know for sure that he would kill her because he says that he would kill people but in return he only saves them/helps them almost dying in the process. So for all we know, he might capture Lydia and make sure to kill her only when she turns into a kanima in front of him.

Derek endured so much trauma. He has every reason to become a villain but he didn't, he became a hero. He didn't go on a killing spree and didn't opt for revenge. If Matt decided to kill all of those people just because they laughed then Derek can kill Scott too for saying "maybe they had a reason" but he didn't. He didn't even scold him for that. He just asked "for what?" and proceeded to explain the situation.

He saved Scott's life even though the wolfsbane is harmful to him too. That's not what a villain does. That's not what a shitty alpha does.

Scott didn't help make Derek a better person. Derek became his own person. If anything his betas, Isaac, Erica, mainly Boyd, helped him to turn into a good person. Not Scott.

Scott has every reason to hate Derek for not letting him have the cure but Derek does too. Derek is hanging from the chains in his own house basement where his entire family died because of his kidnapper who used his body and Scott straight up refused to help him. Who would want to help him get cured after that? Derek even tries to help him when Kate and Allison ambush them but Scott is intended to talk to Allison instead of making sure that him or Derek or both go somewhere safe. Derek is definitely not a villain here.

Derek is definitely not the best person especially in Season 1 and 2. So he recognised his mistakes and turned into a better person by having the best character development but he is definitely not a villain.

Teen Wolf character poll. Round 10

[inlovewhithafairytale]

First time you ever listen to me.

So this is an imagine that I wrote at 1am and I feel is not good at all. But here it is.

Warning: there are mentions of drowning

Yn was stiles stilinskis adopted sister. Being 2 years younger than him made stiles want to protect her from everything that had started to happen in their life's.

Yn was adopted by the stilinski family when she was 4, having been abandoned in a random house she had been brought to the sheriff's station. That day the sheriff's son was there and took a liking to the sweet shy 4 year old. The sheriff and his wife had always wanted to have more kids but couldn't so when Claudia met the little girl who had dark brown eyes and a sweet smile she completely fell in love with her and begged along with stiles to the sheriff to keep the girl.

So that's how you stilinski began her life, she was a smart kid who always had a smile on her pretty little face, but she always liked to be with her big brother no matter what, and stiles liking to have her around at all times placidly complied. When stile and yn met Scott they became inseparable and it was usual to see the two bigger boys and a young girl playing together.

Yn was close to her adoptive mother so when she became sick, and had to stay in the hospital it became normal to all the nurses and doctors to see brunett little girl with a small bouquet of flowers walking toward the room A13

When Claudia died when Yn was 8 she grieved the loss of her mother so bad that the sheriff got worried about the girl who refused to eat and sometimes stayed sitting staring at a wall, her mind somewhere else. Since then Yn became even closer to Stiles and every night she would go to his room holding Mr.bear and climb up to his side.

Years went by and Yn had a pretty normal life till her dear brother decided to go search for a dead body in the woods. That nightt was the time Yn's life would change for ever from that day on she had been included into her best friend's mayhem. Him becoming a werewolf, werewolf hunters, Derek. And the most recent supernatural creature. Kanima. Except they didn't know it was a kanima then.

Yn had been included in the plan to get the bestiary, which they had all formed to see what was the creature who had been lately roaming the streets of beacon hills. The plan didn't really go as expected and yn found herself by the swimming pools.

She had heard voices and went to see who was there. She came into the room just in time to see stiles and Derek go under the water, she went to help them, but her path was intercepted when a horrendous creature in all fours and a tail, pretty much like a lizard. She screamd and ran the other way. She though she could get out of there safely when she heard a snap and felt something slice slightly the back of her neck, right when she was beside the diving pool.

Yn felt her limbs go numb and she fell into the water.

Stiles had just resurfaced. When he though he heard a scream but he couldn't have actually heard it while holding a splashing and very much useless Derek up

"Did you hear that?" Stiles asked Derek whilst holding him up, which became more complicated by the minute.

" couldn't have heard anything while I was bellow the water" he gruffly answered.

Well you're not the one holding us both up"

Derek just grunted in reply when he saw the Kanima wasn't near their pool.

"Where's the lizard?" He asked trying to turn around.

"It was right ther- what's it doing near the diving pool?" Stiles started cutting himself out as he saw the lizard like creature looking into the water one pool away

"You can't expect me to answer that do you?" Replied a very annoyed Derek spitting water our of his mouth.

While stiles and Derek were complaining, Yn was fighting against her own body to get to the surface. She felt her lungs where going to explode as she begged her body to function, but she had kanima venom in her system and it wouldn't wear off in a while. She tried to think, to scream for help knowing that Stiles would come and get her. But the only thing that got out of her mouth were boubles as she sank further in. She felt her head go dizzy at the lack of oxygen. But she refused to open her mouth till the very last moment. She felt herself grow tired as she felt he lungs would collapse, and she let the water in. After a while she didn't feel anything. She fought against the darkness that tried to consume her. She though about her family, her new friends, of her future life. And for a while, it helped her fight. But she soon realized none one was coming to save her. That maybe it was for the better altogether, she'd miss her family. But it was for the better. It was all for the better. And then she closed her eyes and let the darkness consume her.

Stiles felt himself being pulled out of the water and into the ground. He grunted as he hit the floor and he heard derek grunt as well as he fell beside him. Stiles looked up at Scott " thank God, I was wondering when you'd come!"

His best friend gave him a small smile down at him.

" it was a kanima, " Derek said" that's why it turned around when it saw its reflection"

"Where did you leave Yn?" Asked stiles sitting up.

" what do you mean? I left her here with you?" Scott replied furrowing his eyebrows at the boy

"No Scott she left with you." Stiles started to get worried

"Stiles when I leaved I left her here"

"Stiles didn't you say you heard something?" Derek asked him stiffly sitting up

"Yes, I thought I heard a-"Stiles cutting himself up when the truth hit him "oh my God" he quickly lifted himself in his feet and ran toward the diving pool" God please don't let her be in the pool" he quietly muttered to himself.

Scott had quickly followed him helping Derek up.

But surly stiles saw at the bottom the frame of a body. He didn't think twice abou diving in. He quickly took the small frame in his arms and swam back up.

He pulled Yn's body out. Scott looked down at the girl and saw that her lips where blue and her face deadly pale.

Stiles saw it to but he denied the truth, he gently shook Yns body

"Yn common wake up" he said" please don't live me, Yn please common baby wake up" he gently slapped her face but nothing, stiles felt fear gripp him" no, no no no, common Yn, you need to wake up".

Scott was already on the phone calling an ambulance and Derek, being the adult of the group, he quickly took stiles arm." Start doing Cpr"

Stiles could vaguely remember how he started pounding aging Yn chest"one,two, three..." and giving her mouth to mouth. He didn't remember how the tears slid down his cheeks as he tried to bring back to life his little sister.

He started sobbing when he saw she wasn't answering any of his pleads for her to fight. He hit her chest when a gentle cough came from the girls blue lips as the ambulances sirens was heard in the distance.

His eyes widened and he looked back to Scott who had been o the phone whith his mom and giving stiles directions on how to keep doing the CPR properly. " mom she coughed"

" her heartbeat's slow" derek told him and in that moment the paramedics burst through the pool room and to Yns side.

Stiles didn't remember how he ended up in the ambulance in the way to the hospita, holding yn-s cold hand in his. Or how his dad had to hold him from going in with the paramedics while they took Yn to a room to try and bring her back because her heart had stopped again.

Stiles sobbed into his dad's shoulder, dripping wet as he was " it'll be all right Stiles" his dad tried to comfort him when the truth was he was as scared as his son, that they would lose Yn.

Scott was whith them in the waiting room with his mom ad well as Lydia, Allison, Isaac and Derek, who had arrivquickly after Scott's mom called them. They were all extremely worried for the girl that had brought so much happiness into their life's with her shy way, the way she smiled and the way she was always there for people when they needed someone.

Aftera few minutes the doctor came out with sober look in his face. " we're sorry but Yn haven't survived." Everyone in the waiting room gasped at the words, everyone's eyes watered at the though that such a young life would be ended so unexpectedly. Stiles looked up tears falling from his eyes.

" Can I see her?" He asked quietly as he cleaned his cheeks from tears only for new ones to take place.

The doctor nodded and stiles went into the room where his sister laid motionless. He chocked a sob put as he looked at the once face that was so full of life a few hours ago.

"Why did you leave?" He whispered to her." Please fight, Yn I need you, please, you can't go. Don't live me like mom did."

Stiles took her hand in his and gently squeezed it as he cleaned his face with the sleeve of his shirt, only to realize he was still wet form half hour ago.

Then out of nowhere a gasp came from Yns lips and she shot up from where she laid . Stiles jumped away from her in surprise and the doctor and his dad rushed to the door of the room to see what was happening.

"Yn?" Siles whispered to his supposed dead sister.

When Yn turned to him stiles saw that her eyes were glowing violet but quickly faded to their natura brown color when she saw him.

"Stiles" she gasped out before stiles tackled her in a hug holding her close.

" I thought you were dead" he said against her damp hair.

"I heard you telling me to fight"

" well first time you ever listen to anything I say" he muttered holding her tighter against him.

So part 2? This took me so long to write. Hope you guys like it

[princeescaluswords]

Hey Prince Escalus! I have seen your work and posts for quite a while actually and I admire your credibility and honesty with debates, questions and answers in the Teen Wolf universe. Especially with the characters, their strengths and flaws, the plot and storyline, the motives behind every character, how the villains are portrayed and even pointing out the very mind boggling tropes and disputes that occur from the Fandom and is placed in the characters of Teen Wolf.

I was rewatching season 2 the other night and there were a few things that did caught my eye and confused yet intrigued me at the same time. It's when Lydia does give the key to Jackson the first time in 2x05 (Venomous), but Jackson still transformed into the Kanima after the Hale pack invade Scott's house to murder Lydia. But what caught my eyes more was when Lydia touched Jackson's arm in 2x09 (Party Guessed) it looked as if Jackson partially snapped out of the trance he was in as the Kanima briefly from her touch and presence, until she left after he warned her that she shouldn't want him to come to her party. Then again in 2x12 (Master Plan), Lydia's presence and her giving Jackson his key reverted him back from his Kanima form to regaining his human features. I was brainstorming, could it have been Lydia's emerging banshee abilities that had that affect on Jackson? Or was it because Jackson was under two different Kanima Masters, where the first time it didn't work because it was Matt and he had a strong grasp on him whereas with Gerard, after being defeated, the link between him and the Kanima was weak that it allowed Lydia to bring Jackson back? I was thinking alot about this since it was rather intriguing. What would your thoughts be on this?

I think all these things contribute, but I think that the primary answer lies in the details of the scenes themselves. While Lydia presents the key to Jackson in both scenes, the conditions of those presentations are entirely different.

In Venomous (2x05), Stiles, Allison, and Jackson have spirited Lydia away to Scott's house to protect her from Isaac and Erica, who were planning to kill her on Derek's orders. They haven't told Lydia why (which they will all later realize was a mistake) and she's confused and defensive as a result. While Jackson may want to protect Lydia, he's still convinced that someone broke into his house and edited the tape he made of himself turning into a werewolf, and he thinks it might be her. So in this scene, the key isn't evidence of their connection, it is evidence of people deceiving him.

Jackson: Where's my key, Lydia? It was you, wasn't it? You edited the tape. Lydia: What tape? Jackson: The night of the full moon. The recording. You came into my house - into my room - and you saw what was happening to me, so you took the tape from the camera and you edited out the most important part. I don't know why. Maybe because you wanted to take that from me, my moment, like you take everything. Or maybe you just thought you were protecting me. But it was you, wasn't it? Lydia: I don't know what you're talking about - But if you need it so badly - Fine. Lydia: I hate you. I hate you so much. Jackson: No. No, you don't.

She doesn't reach Jackson when she presents him with the key this time because the emotions behind it are all wrong. He's convinced she is denying him the identity he desires. But then, right before he transforms into the kanima, he realizes that she does have real feelings for him, which he doesn't understand. Jackson didn't become the kanima because he wanted to be a reptilian murder-slave; he wanted to be a werewolf to be special, which means he would be valuable to someone. (The irony of course is that he was already special and valuable; he just doesn't believe he is. Impostor Syndrome FTW!) The key doesn't stop him from becoming the kanima because it doesn't reinforce his own identity; in fact, in this instance, it confuses him even more.

Now, we move to Party Guessed (2x09) where Lydia goes to Jackson to personally invite him to her party, because she does care for him. Jackson is being influenced by the kanima identity (and Matt), but when she touches him -- now that he knows she cares for non-supernatural Jackson -- it shocks him momentarily free from the kanima transformation. (The irony here is that she is offering a way back to himself even as she slips farther under Peter's control.) His look of loss when the touch breaks off is real, and it helps set up the terms and power in the final scene you mention.

The situation in Master Plan (2x12), when Lydia presents the key again, is completely different than in Venomous. This time, Jackson isn't pursing her to get the key and solve the mystery of why he didn't transform; this time it is Lydia who is seeking him out because getting the key back is what Jackson wants. It shocks him, just like the touch in Party Guessed did, because she is here for him. For Jackson. Not for the kanima. She calls his name, peeling back the kanima's identity, and he remembers how he gave her the key in the first place.

Jackson: Do you - do you still - Lydia: I do. I do still love you. I do, I do still love you. I do. I do. I do still love you, I do.

Peter wasn't just spouting romantic nonsense when he talked about the power of human love. Love, real love in all its forms from romantic to familiar to platonic, is an expression of absolute care for another person. In this case, Lydia loves Jackson -- Jackson's original identity -- because of their relationship and not through some supernaturally enforced master-slave relationship, such as the ones which existed between Matt and Jackson and exists between Gerard and Jackson. Those two villains didn't love Jackson, they were using him. Lydia isn't getting anything out of this act; on the contrary, she could straight up die since Gerard ordered the kanima to kill them all. This is made real to him by the presentation of the key, because Lydia understands he "need[s] it so badly" that she came to this dangerous place for him.

While I do believe that there is power in Lydia's voice, Peter was right again when he said it's just a tool. In this case, the power of the voice "drowns out" everything for Jackson but the "real connection" forged between Lydia and Jackson, which, as Peter put it in Battlefield (2x11), is "disappearing beneath a reptilian skin and [she] needs to bring him back."

And so she did.
