Chapter 10: More Dangerous than Me? 

Allison is bleeding out, and no one knows what to do.

“Y/N! Do something!” Her hands start to shake. 

“It’s too deep, she might drown if I just close the outside, or her throat might swell closed. I can’t…I told you I can only do surface wounds.” She backs up until she hits something solid. She jumps when she feels hands on her arms. She looks back to see she’d backed right into Diego. 

“I’ll only make it worse. I could kill her,” she says, her voice small and almost too quiet.

“It’s okay. We’ll figure it out,” he tells her. He rubs her arms to try and offer her what little comfort he can.  

They rush to get Allison back to the academy.

“Come on! Let's go!” Five shouts when they get there.

“I don't think she's breathing,” Luther tells them.

“If we don't get her upstairs," Klaus says as he goes to help Luther carry her. "She's gonna die.”

“She's suffered a severe laceration to her larynx,” Grace informs them once inside and in the med room.  “One of you will need to give blood.”

Luther, Klaus, Five, and Diego volunteer. Luther insists on doing it.

“I'm afraid that's not possible, dear boy,” Pogo sadly says, “Your blood is more compatible with mine.” Grace and Pogo continue to gather what they need.

“Hey, don't sweat it,” Klaus tells Luther. “I got this, big guy. I love needles.”

“Master Klaus,” Pogo starts. “Your blood is, how shall I say this? Too polluted.”

“Move,” Diego steps in.

“Yeah, go on,” Klaus says.

“I'll do it,” Diego rolls up his sleeves but faints at the sight of the needle.

"Oh, for the love of-" Y/N takes off her jacket and throws it at Klaus before holding her arm out for Grace to prepare her arm for the needle. "I'm going to put most powers of my into the Wisp so that there hopefully won't be a temp difference. Though a tiny bit might actually help, I'm no expert."

"It should be fine," Pogo assures as he and Grace get back to work. 

"I should be doing it," Diego crouches beside her once he came to. Someone had brought her a chair. The room was quiet now that Pogo and Grace had managed to do what they could to save Allison. Luther refuses to leave Allison. Grace stays in case she is needed. Diego continues, "You're too exhausted, and you're-"

"You passed out just looking at the needle, and are you forgetting you have a bullet wound too," she tells him. Something in her stressed and sleep-deprived mind has her fingers twitching to brush her fingers along the scars on his face because of how close he is and how sincere he is being. But she fights that urge.

“I lost less blood because of your hot hands,” he says, earning him a small chuckle. He takes that as a win. She's been on edge and too serious all day. 

“I’m okay, tough guy,” she assures him. "At worst, I get a bit woozy. Either way, Allison gets what she needs. That's what matters. And you avoid the needle." She pinches his arm and grins. He glares, but there is no heat in it. "You don't have to stay if it makes you uncomfortable." She gestures to the needle and tubes.

"I'm fine," Diego tells her.

"I'm probably just going to close my eyes and switch to the Wisp."

"All the more reason to stay," he states.

"You're going to hover until this apocalypse thing is sorted out, especially after what happened at the rave and this." She gestures to Allison.

He doesn't answer but still hasn't moved from where he's crouched beside her.

"Right," she chuckles, and she pats his cheek. "Sad it took the end of the world for you to turn so sweet, cariño."

He’s taken aback by the term of endearment, but he doesn’t hate it. He does technically call her one constantly. Mi Luz. It was a common term of endearment. He shouldn’t be so surprised. Then again, it might be the exhaustion and the blood loss talking. Even if it is a controlled loss. "We'll stop it," he assures her as he removes her hand from his face but keeps it in his own. It felt unnaturally cold for her since she had willed so much of herself into the Wisp, for Allison's sake. He stood up but kept her hand, warming it some between his own. "Maybe you should get some sleep," he suggests. She shook her head. "Why not?" he adds.

"Because this is not a time to risk losing my control. It's a balancing game when it comes to my powers. How much focus and power I have and where it is can change everything. If I touch something, it will burst into flames if I touch it too hot. Will my watch band melt or my shoes? Just because I wasn't thinking. Allison is in too fragile a state to risk anything."

“Then I guess we wait,” Diego states. And they all do. Only leaving when Grace tells them it’s enough and removes the needle. Luther, of course, stays with Allison.

“You should go lie down,” Diego tells her. “You used your powers a lot and are low on sleep and blood, mi luz.” He decides to just lean into the whole endearment thing. 

“I’m fine,” she assures him and smiles. She laughs a bit at his skeptical look before adding, “I’ll go down and get a drink and snack. Like when you donate blood. I’ll be okay. Just got to hydrate. We don’t have time for me to be out of commission. I will relent to you hovering and a snack. Deal?”

“Deal,” he says. It might be the blood loss and lack of sleep, but she feels unusually bold and kisses his cheek before she hurries off to the kitchen. He is stunned and just watches her go. He stands there way longer than necessary before he grins to himself and goes to find the others. 

“The bastard that nearly killed our sister's still out there,” Diego tells Five and Klaus. “With Viktor.” 

Y/N hurries her pace toward them. 

“We need to go after them.”

Five disagrees, “Viktor is not important.”

“You can’t be serious,” Y/N says as she reaches them. A sandwich and a glass of juice in her hands courtesy of Grace. “V is family.” Diego goes to stand beside her as she speaks. He sees her brows furrow. Unbeknownst to him, she wonders when he last ate. He’d spent so long with her, and before that, he’d been in jail. She offers him a bite of her sandwich. He rolls his eyes, but when she doesn't move to lower it, he takes a small bite. He thinks it was worth it when she smiles at him. But he turns back to focus on the important discussion he was having. 

“A little heartless even for you, Five,” their brother points out.

“I'm not saying I don't care about them,” Five admits, “but if the apocalypse happens today, they die along with the other seven billion of us.”

“Harold Jenkins is our first priority.”

“I agree.”

“Let's go.”

“You guys count me out,” Klaus says. “I mean, you know, no offense or whatever. It's just I kind of feel like this is a whole lot of pressure for newly-sober me, so -” 

“You're coming,” Diego states. Y/N just sips her juice and watches her chaotic siblings. 

“No, no, no,” Klaus says. “I mean, I think we can all agree that my power's, I mean, it's pretty much useless. I'd just be holding you guys back.”

“Klaus, get up,” Five says.

“You can't make me.”

Diego hurls a knife at the couch Klaus is sitting on. Y/N rolls her eyes.

Klaus gets up. “Oh, then again, a little exercise couldn’t hurt. Yeah.”

"I'll check the area," she summons several orbs. 

“Fine, but stay behind me,” Diego tells her, knowing most of her focus will be elsewhere. She rolls her eyes but humors him, even going as far as to grip the back of his shirt. She uses several Wisp orbs to search the area outside the cabin, finding nothing. She shakes her head and focuses back on the scene Diego had led her to. The very dead body of Leonard Peabody, with numerous knives and other projectiles embedded in his chest. She winces as she lets go of Diego. He looks back at her just as her eyes return to their normal color. She shakes her head when her eyes meet his. They both turn back to the dead body on the floor.

"I have seen more than most," she says, leaning against the wall. "But even this is…yikes."

"It's not exactly what I was expecting."

"The understatement of the year."

"No sign of Viktor," Klaus says. 

"Not outside either," she adds. 

"Let's get out of here," Diego says. "Before the cops come." He shakes his head at her when she goes to offer the Wisp to act as a lookout. "You are too burnt out, and we may need you later."

"In a minute," Five says.

"Come on, Five, what are you-"

"Ugh, wow." Klaus retches as Five checks the prosthetics eye against the dead man's eye.

"Same eye color, same pupil size. Guys, this is it. The eye I've been carrying around for decades, it- It's found its rightful home."

“Gross,” she states, and Klaus agrees. 

"We got the guy we needed to kill to stop the apocalypse."

"Yay!" Klaus says. "Let's go." Diego stops him.

"No, no."

“What?” she asks. 

"It can't be this easy."

Five frowns. "Look, this is the note that I got from the Commission."

"The one that says, 'Protect Harold Jenkins,' aka Leonard Peabody."

"Yeah?"

"But who killed him? Who did this?"

“No one is here,” she points out. 

"I have a crazy idea."

“When don’t you?” she sighs. Klaus nods in agreement. She knows that time is running out. She’d tracked the police response times far too many times. She was starting to get anxious at not checking to see if they were close. 

"Crazy, but why don't we find Viktor and ask what happened? If Viktor got away from this asshole, he might be headed back to the Academy."

Once at the Academy, she finally lets Diego talk her into getting some sleep. But only if he stays with her. He relented. But he had snuck out at some point. She woke up alone and let the Wisp drift around until she heard fighting and the sound of something shattering. She was on her feet as fast as possible. She hurries into the living room.

"What the hell is going on?" She rushes to where Diego is unconscious on the floor. "Five?" 

"He'll be fine." She glares at him before going back to checking Diego over. He groans as she runs her fingers through his hair, looking for injuries, and she finds a sore spot. Earning a laugh from her. His eyes snap open at the sound and the feeling of fingers along his scalp. He stares up at her. She smiles down at him.

"You good, cariño?" She asks quietly. Her fingers are still searching for injuries. 

"Y-yeah," he manages to say. He clears his throat as she pulls away. "Yeah, I'm good." He remembers that he’d been fighting Hazel and is on his feet as fast as he can manage. She watches him curiously before she is pulled to her feet and against him as he looks around the room.

“No one’s here,” she assures him. Diego nods. Y/N huffs a laugh and pats his chest as she pulls away from him. She still has no idea what has just happened, but he was back on his feet. Diego lets her go and glares at Five. 

Five looks back at him, gaze shifting over to his sister before focusing back on Diego. “I am curious. Your girlfriend, Patch.” He emphasizes the name. Again looking between his now oddly close sibling. “What did you like about her?” 

Diego hesitates a bit and looks between his siblings. His gaze lingers a bit too long on his sister, who looks back at him with a curious look. “This should be interesting,” she mutters, stealing a drink of her Five’s margarita. He snatches it back. “None for you. You’ll have more alcohol than blood in your BAC.”

“Fair point,” she admits before grinning at their other brother. “We’re still waiting, Diego.”

Diego rolls his eyes at her but answers, “A lot of things.” He thinks about it and adds, “Cute butt, nice legs.”

She chuckles. "Classy."

“Anything a little more profound than that?” Five asks.

“She believed in people,” Diego says. “No matter how much shit and filth she saw,” he glances at their sister again. “On the streets. She always saw the good inside.”

“Well,” Five acknowledges his answer. “I'm sure she'll be proud to know that you're killing Hazel and Cha-Cha as a way to honor her memory.”

Diego looks to Y/N. She gives a half-hearted smile. Her eyes are sad. She hadn’t known Patch well or for very long, but she found her first. 

“Guys! No, let me -” Viktor shouts from inside the bunker. 

“You locked up our brother because you think he has powers?” Diego and Klaus are shocked. 

“No, I know he does,” Luther answers. “Pogo told me. He's always known, and so did Dad.”

“Why would they hide this from us?” Diego asks. “I mean, am I the only one that didn't know this place existed?”

“He hid so much from us.”

“He hid it because he was afraid of him.”

“Oh, that's ridiculous.”

“Is it? Dad's lied about everything else, why is this so far-fetched?”

“If you're right, then maybe he's the one who killed Peabody.”

“And cut Allison's throat.”

“Whoa, no.”

“Let's I ju- Sorry, just, let's go back, all right?” Klaus says. “This is Viktor we're talking about. Our brother. The one who always cried when we stepped on ants as kids.”

“Yeah, I know.”

“What the-” Y/N hurries into the dimly lit room. “Let him go.” Her eyes begin to glow as the Wisp takes full form.

“I can’t do that,” Luther says. “Just let me-”

“Now!” The Wisp crackles and burns like full-on flames. Bright yellow and orange flicker in the air above them. Her eyes lit to match. The heat distorts the air around it.

“Guys,” Luther starts. “I know it's difficult to accept. If you just let me-”

“It's not difficult to accept. It's impossible to accept,” Klaus continues to argue his point.

“No, they're right,” Diego speaks up. “Look, we can't keep Viktor locked up without proof.”

“Wh- What more proof do you need? Why don't we just open the door and ask?”

“No, he's not goin' anywhere.”

"Like hell, let him go," she looks between her brothers. 

"Sorry, Y/N, it's for the best," Luther says.

"Bullshit! He's afraid," she says before sending a small Wisp toward the bunker. The smaller one is a softer, calm Wisp as the majority of her powers continue to burn above her and Luther. Tears in her own eyes evaporate to steam as she takes in the fear in Viktor’s eyes. She focuses back on their supposed leader. “This is insane, Luther,” she hisses at him. Flames dance in her eyes as she glares at him. Klaus wipes away sweat as the temperature in the room rises. He glances at Diego. Diego looks between his siblings. He has to defuse this situation before it gets worse.

“No, even if you're right, Luther. Viktor needs our help,” Diego points out. “And we can't do that if he's locked in a cage.”

“Do you really think Viktor is any more dangerous than me right now?” Y/N states as the Wisp moves closer to Luther. Her hands now glowing as she steps towards him as well. Diego knows this could go very bad, very fast. It’s worse than someone burning a candle at both ends. This is like someone threw gasoline on a raging fire. 

"You don't want to do this, Y/N," Luther says.

"Going to lock me up too?" She challenges. "Good luck with that. Try and lay a finger on me, Number One. I dare you." She rips her watch off, and it melts in her hand. The smell of burning plastic and metal made most of them flinch. Viktor just stares. He’d never seen his sister this vicious. He glances at the smaller Wisp in the bunker. It was odd how its gentle blue light contrasted with the angry figures outside the bunker. 

"That's not-" Luther starts. He looks over at Diego and Klaus. "This is what needs to happen."

Diego shakes his head and focuses on her. She might actually listen to him. He needs her to calm down before she does something she can't undo. "Luz, you need to give yourself a break," Diego says as he moves closer. “We can handle this another way.”

"Not while V's in there," she refuses. "I won't leave him in the dark, alone. I didn't have a choice with Ben. I have the choice now."

“What good are you to Viktor if you waste all your energy on Luther?” Diego urges her to ease off. Her eyes snap to his. "First, it's finding Five, then Klaus, then Luther and Klaus again, Allison, now this. All while searching for Viktor. There isn't going to be any of you left if you don't take it easy."

"If we fail, we all die anyway, Diego,” She tells him. Tears turn to steam again as her eyes turn to fiery blue. “Why stop now?”

She’s hurting, and he knows it. She can’t keep this up. She’s running on rage and adrenaline, but those never last long. “Because you’re not alone in this fight. We can help Viktor without you burning yourself out.” He turns towards Luther. “And we are helping Viktor.” 

“Yeah,” Klaus agrees with Diego. “And for all we know, Viktor might be struggling with this new power. I mean, it must be scary. Terrifying, really, to discover that you can do something that you never thought you could do.” 

Diego sighs as that seems to do the trick, and she drops the raging fire that is the Wisp and moves over to the glass. The heat leaves her hands as she reaches for the glass. Her eyes lack the rage and heat they had before. She puts more of her powers into the Wisp inside the bunker with Viktor. She keeps it as calm and comforting as possible. Like she would on the nights Klaus and Ben would hide from the darkness in her room. "I'll stay with you, V. I promise. I'll stay with you in the dark."

“Look," Luther keeps arguing his point. "If what Pogo told me is even half true, then he is not just a danger to us.”

“I don’t care,” she says. “I’m not-”

 They all turn as Allison comes in. Y/N moves to lean against the wall beside the door, the Wisp still in with Viktor. She focuses on giving off a comforting feeling. She sends all the love she has into the Wisp. 

“Allison, what are you doing down here?” Luther asks. “You should be in bed.”

Allison writes on the notepad to let Viktor go.

“I can't do that,” Luther tells her. “She hurt you.”

“I'm sorry, but she's staying put.” Luther tries to assure her. “Just until we know what we're dealing with.”

Allison is clearly not happy with the answer. An angry noise leaves her damaged throat. 

“She stays put,” Luther adds. 

Allison tries to go past Luther, but he stops her. She pushes at him. She silently cries as she hits him.

“Come on,” Luther starts.

Allison sobs. 

“Come on,” Luther repeats. “You need to rest.”

“I'm sorry! I'm sorry!” Viktor looks up at the Wisp and then back through the glass. “Y/N, please!”

“The Wisp won't leave you, V. I’ll still be with you.”

“Then the rest of you needs to rest,” Diego insists. 

“Let's go.”

“No! No! No! No!” Viktor calls after them. 

She lets Diego lead her toward her room. “I wonder if he would have made a room for me if I hadn’t been so willing to-”

“Don’t think like that,” Diego tells her.

“Why not? We have similar powers. V uses sound. I use light. It’s tied to my emotions, just like V’s. I could have easily taken Luther out or even melted that door. Especially as the Wisp. I don’t even know if there is a limit beyond how much oxygen there is in a room as to how hot I can heat it. I could burn this entire place down with everyone in it if I wanted to.”

“But you don’t want to,” Diego counters. “You have more control.”

“Do I? I lost it at the rave. I meant what I said down there. How is Viktor more dangerous than me?” She asks. “How do we know that? Because Luther says? Diego, we-” The blood drains from her face as she realizes what Viktor is about to do. She can feel it in the air inside the bunker. She focuses a bit more on the Wisp.

“Cari…” She starts as she looks at him, her eyes glowing bright blue from her powers. The brightness contrasts with her paling skin. 

Diego is immediately concerned. He reaches out in case she passes out. 

 “Run,” she tells him. 

Then all hell breaks loose. 

“Cariño”/”Cari” Dear, Sweetie, Honey, etc. Term of Endearment 

“Mi luz” My light, Term of Endearment
