The Roommate

Summary: Theo Dimas has sins to atone for. Maybe letting Mabel move in can help him do that just a little.

Theo Dimas wasn’t sure what prompted him to ask Mabel to move in. Mabel was part of his past. Zoe’s death, the thing that had haunted his nightmares for so long. He’d avoided her. When she moved into The Arconia again, he used to wake up in the middle of the night, sweating. When was she going to tell the truth? When would she ruin his whole life? Then, the truth was found out, and in a weird way…his life wasn’t ruined.

Because when Mabel came, his dad went away. The minute Teddy Dimas was gone, it was like Theo could breathe again. His secrets were no longer hidden. Which was why, when he found Mabel crying outside of The Arconia, he couldn’t help but stop and ask her what was going on. Mabel had freed him from his darkness. The least he could do was help her in whatever way he could.

In a shuddering breath, she told him, “I can’t find an apartment. It’s too expensive, and the only way I could afford to stay is if I sell out to Cinda Canning…I don’t know how I’m going to tell Oliver and Charles.”

Theo made a face. You can’t do that, he signed to her.

Mabel nodded and wiped her tears away. “I know I can’t. But how else can I afford to live in the city? I’ll have to go back home…”

He owed Mabel Mora everything. The least he could let her do was stay at his place, rent free, and maybe atone for his sins a little. If such a thing was possible for someone like him. Stay with me.

Mabel squinted at his hands, as if she wasn’t sure she had understood him. “Theo…. I can’t stay with you. Wouldn’t that be too weird?”

Theo shook his head. Only if you make it weird, he signed, I’ll even help you pack your stuff.

Mabel laughed. “You don’t have to do that.”

He insisted.

It took them one day to move her in, and less time to help her pack. It was the easiest choice Theo had ever made in his life.

Only Murders in the Building | 3x08

[potterandpromises]

@darkerstark said: How about some "missing scenes" from 4x01? Like Mabel and Theo having a little friendly/flirty chat while she's packing her things for L.A. (he casually asks if she's going to meet up with Tobert there and she's all like Tobert who and he mentally files that under Very Interesting)?

On the floor by Theo’s coat closet, Mabel rummages through her moving boxes. She needs something for a meeting with some Hollywood bigwigs, plus something for a party or two. She never unpacked, nor has she managed to keep her things neatly storied.

She’s sorry for the mess, for how long it’s been here.

Theo opens the door. “Thank you,” she signs with both hands, “thank you, thank you!"

Mabel had storied her suitcase in Teddy Dimas’ empty apartment with the rest of the things she didn’t normally need. Something she'd only remembered an hour ago. She texted Theo to vent, and 15 minutes later he was facetiming her from a Target.

He smiles, a bit bashfully, and sets the new suitcase down.

She rips the tags off, tugs the zipper open, and retrieves a tan jacket from one of several boxes labeled clothes. She folds it haphazardously, and Theo watches, thoughtful.

She pauses, and still a bit high from his generosity, smiles at him like 'what?'

(A solid 20% of their communication is solely through smiles and eyebrows.)

“I was just wondering…” he pauses. Oddly. “Are you going to visit—“

His fingerspelling is too fast for her and he has to repeat himself. “T-O-B-E-R-T."

“Oh, ah, I don’t think so?” He’d texted her a photo of the airplane wing when he landed in L.A. and nothing sense then. He hasn't really been on her mind, she realizes. Maybe if she were in the city longer and they were old flames or something, it’d be nice to meet up, but she’s only going to be there a couple days, and why string him along?

Theo crosses his arms, creases his eyebrows, tilts his head like if he changes the angle it’ll make her make sense.

“No,” she signs, “I’m not going to see him.”

Theo nods, and there's something in his expression—a lip bite, a shift of his gaze—she can't quite decipher.

That point when you're 2/3rds through writing a long fanfic:

[harrietmjones]

I’m currently working, albeit very slowly, on the third chapter in this OMITB fic of mine.

Currently, I’ve done a layout for about five chapters so far, which I’m gearing towards completing at some point.

Hopefully it’s not too bad, my writing. I lack so much confidence, I need to tell myself to stop the self doubt!

[the-apple-of-her-eye-au]

WHOOO! Some more radioapple for you lovelies, including a little musical moment!

[maineshewrote]

Same word, different font

Soft comfort character persuaded to give an uncomfortably impromptu performance of a sweet familiar song which changes entirely in the middle of the performance thanks to an extremely lucky otherwise pointless side character who gets up to sing with her idol in a stage-like setting in a living room with no planned choreography which turns out beautiful

My Fics are All Over the Place

And most of them are smutty. All AO3 links because everything I write turns out long. An incomplete list:

Another Day in Paradise (Hazbin Hotel, Adam x Fem!OC, offensive language bc it's Adam and violence bc it's Hell, currently 100k and still going, my current baby)

Unspoken (Only Murders in the Building, Theo x Fem!Reader, 18+, 84k words, love and angst)

The Best Revenge (Hannibal, Chilton x Fem!Reader, 18+, 81k words, also love and angst)

Coattails (2012 The Lorax, Oncler x Fem!OC, 18+, 54k words, yes I went there but I am REALLY proud of my take on it)

Dangers of Working with Ferric Oxide (Venture Bros, Rusty x Fem!OC, 18+, 100k words, particularly fond of my OC in this)

Fumbling with the Future and Falling for the Future (2021 Encanto, same story from two different POVs, Bruno x Fem!OC, about 71k between the two, amazing NOT 18+ but there's a TW to make up for it)

With Wandering Steps and Slow (Ghost fandom, wip, Terzo x Fem!Reader, 18+, 23k words so far, lots of angst)

The Peach (Ghost fandom, wip, Cirrus x Fem!Reader, 18+, 35k words so far, kink and cuteness)

Flipping the Script (toes the line of original work because I based the whole thing on a four-minute song, standard M/F romance but I think I did a really good job on it nonetheless, 18+, 107k words)

Fireflies and Auto Theft (Gravity Falls, I did a whole series of these and they're honestly pretty good stories on reread so I guess I'll link them, Stan x Fem!Reader, 18+ even though it's a kids show I know I'm gross, 76k words)

And there a few one-offs and side-stories floating around my AO3 too.

Just a Little Cheesy

Summary: Mabel moves in with Theo and enjoys perks like grilled cheese sandwiches and kissing in the kitchen.

A/N: I'm not sure what I think about this, but now I've gotten obsessed with Mabel and Theo being roommates and I can't let it go.

Everyone seemed to be happy. Oliver was happy with Loretta. Charles was happy with his show. And Mabel…

Mabel didn’t know what she was anymore. It was strange to think that she was happiest whenever her life was dealing with death and chaos and murder. After all, that was what kept the podcast going, wasn’t it?

It touched every part of her life. Every time she dated someone, there was always the chance they were the killer…and that, Mabel realized, was growing wearisome. She wanted someone she could trust. But it was hard when she was in the business of distrusting people.

But then…Theo happened. Like most things Theo did, when he offered to let her move in, it was so softly asked even in his gestures that she almost wouldn’t have noticed it. She didn’t want to impose or make Theo think of all of the bad things they’d gone through. “Are you sure you can handle it?” she asked him.

Theo only smiled. “Move in day is tomorrow,” he signed to her.

She was aware of every move she made because of the silence her first week at his apartment. The slamming of a door, the creaking of floorboards…

But there was something comforting about it. She was aware she was alive. Something that had been very hard to do since her teen years, since losing Zoe, Oscar, and Tim all in different ways. Before Oliver and Charles, it had felt like she’d been invisible almost.

Or maybe even dead herself.

Or at least half-way there.

Most people, Mabel suspected, would have been unnerved by the silence. But the silence comforted Mabel. It meant she was safe. Protected. Something she hadn’t been in a very, very long time.

Mabel had someone waiting for her to come home. And that was a novelty. Mabel had thought that maybe because of all of the death surrounding her, she was destined to be alone. But Charles and Oliver had proved that theory wrong.

But Oliver had moved on with Loretta. And Charles was busy with the show. They were still working on the podcast, but it wasn’t like how it had been before. They had their own things. And Mabel…

What did Mabel have, exactly?

The podcast, yes, but there was still something missing that she couldn’t quite put her finger on.

One night, when she was up late editing, she looked up at the sound of a plate being put in front of her. Theo smiled at her, and signed, “You haven’t eaten all day.”

Mabel smiled at him. “Thanks. You didn’t have to…”

He waved it off, and went to go to the living room. Usually, he watched it just with the sound off, and the captions on. But the sound was on, and Mabel had taken that as an invitation to come join him.

She realized there was a crick in her neck. Her body was sore from sitting in the chair. She stretched, then glanced at the meal Theo had made for her. A simple, grilled cheese sandwich with a soda. Mabel shut down her computer then took the meal over to the couch where Theo was sitting.

They settled in, and watched an old re-run of Cold Case. Mabel ate the grilled cheese sandwich and coke, and maybe because it had been made by someone with love, but something about that meal was the best one she had had in a long time.

“Good?” Theo signed when she finished.

“Very good,” she signed back with a smile, “Thanks.”

He blushed a little, and Mabel found herself using his shoulder as a pillow. She didn’t even make it through the whole episode before she fell asleep. When was the last time she had fallen asleep on someone’s shoulder? She didn’t know. What she did know was, that Theo Dimas made the best grilled cheese she had had in a long time, he let her move in without hesitation, and didn’t find it at all weird that her hobbies were murder and her two best friends were two old men.

In the morning, Mabel woke up, with the intention of telling Theo…well, she didn’t know what she was going to tell Theo. But Theo wasn’t on the couch when she woke up. Instead, Mabel found a pillow under her head, and a blanket wrapped around her. Smiling to herself, she got up from the couch and went to look for him.

He was in the kitchen, cooking pancakes and eggs. There was already a cup of fresh coffee waiting for her next to his. She smiled, and came up behind him, wrapping her arms around his waist and resting her head on his shoulder.

He jumped a little, but smiled when he turned to see her. He put the stove on low then turned around to look at her. “Sleep okay?” he signed.

Mabel nodded. “Yeah.” She studied him for a moment. When she had known him as a teenager, she’d been too wrapped up in Tim, while having a crush on Oscar at the same time, to give Theo a second glance. Their interactions had been minimal at best. The Arconia was a world of money and privilege that knew insiders from outsiders. Mabel had always felt a little bit like an outsider, even with her friends.

Theo, who had lived there, had sensed that about her, she thought. She remembered as a kid she’d sit out front reading and sometimes, he would be out there too. They wouldn’t say anything, but they’d sit in a comfortable, unacknowledged silence. Sometimes, she would smile at him in the elevator. She should have included him more. If only the others hadn’t been so afraid of Mr. Dimas, maybe they would have…

“Something wrong?” Theo signed when she didn’t say anything for a moment.

Mabel shook her head. “I should have noticed you sooner.”

He smiled softly at her. “Are you noticing me now?” he responded with his hands.

“Yeah, I definitely am,” Mabel told him. She reached up and ran hand through his hair. Theo grabbed hold of her wrist, and locked eyes with her. This was it, Mabel thought, this is what I’ve been waiting for.

He kissed her then, and Mabel kissed him back. Like they were in some, cheesy, roommates-to-lovers-romcom. And Mabel didn’t mind that one bit for a change. With Theo, she could handle cheesy.

So, fun fact: I write my fanfic out of order. If I get stuck after a chapter, I just jump ahead to whatever part after I'm most excited to write. So I'm thinking I'll start Tumbling small snippets of future chapters of my WIPs (already written) just for giggles.

[potterandpromises]

@darkerstark said: Or them discussing Mabel's feelings about how she's portrayed in the script and having a slightly meta heart to heart about who they really are and how they're perceived by others?

Mabel eats takeout with Theo in the four-poster Eva gifted her. What, she wonders, would Bev Melon and Marshall and the Brothers sisters think of this?

Theo puts his fork down. Her thoughts must show on her face. "What are you thinking about?"

"How the people who are making a movie about us think I'm a homeless, jobless, mumbling millennial."

He scrunches his eyebrows together. Oh God.

"They say I mumble," she signs, and points to her lips because she doesn't know the sign for 'mumble.'

He nods like, yes, of course, we all know this.

"It bothers me that they aren't entirely wrong."

He shakes his head emphatically, which surprises her, because, well. "You are so much more then what the world thinks of you."

"You too."

He smiles sweetly. She looks away, turns back. "Did I sell myself?"

Did she sell his image, too? When her and the guys started the podcast, she didn't know who he really was.

"Yes," he signs without missing a beat. "Or, you sold the idea of you."

"Yeah."

"But that'll never be you," he signs. "They'll never know you."

There's something behind his last statement, behind his eyes, but that investigation can wait.

I love when Marty Short plays the villain. And if he’s singing?? We’re all blessed. That being said, I love his and Meryl’s For the Sake of a Child. I want more of that voice, that passion in Oliver Putnam. And that being said, can anyone write a fanfiction with Oliver being, well, like that?? I’d pay you with my OMITB like scenes 🙏✨

[essentialalls]

I love every single one of you who writes only murders in the building fanfic in those days. Mine (fanfiction) it is instead a rewrite and I'm writing the s3 in these days just to keep me company, but you know, it's in Italian so obviously it destined to remain in my USB stick (also it's not olicharles so it's not that interesting xD) but here, this is me who loves all of you who can write omitb fanfic and be read by many ♡ you deserve all 💯💛
