She watches them walk out of class together and has the sudden urge to punch something as hard as she can.

She knows that Stephanie is just a friend to him, an assigned partner for a class project, but did the class project have to take all semester? And did this partner have to be so damn attractive?

The worst thing about it is, when she watches them together she can't help but think that Stephanie is more of a match for him. She's upbeat, charming, and confident. She loves movies and has seen almost all of them, it seems. She laughs at everything he says rather than rolling her eyes or mocking him for being a dork. She clearly doesn't have a problem with being affectionate, as Beca observes the way she casually touches his arm while they talk.

"Hey Beca!" he greets her, noticing that she's waiting for him. He walks over to her, Stephanie trailing a few steps behind him.

"Hi Stephanie," Beca smiles thinly, and the blonde nods in response. Beca crosses her arms across her chest, wishing for a moment that she didn't have trouble with public displays of affection, and that she hadn't complained the few times Jesse had tried to touch her or kiss her when they weren't alone.

An awkward few seconds pass before Stephanie turns to Jesse and says, "Ok, well I'll see you tomorrow," and nods curtly at Beca as she turns to leave.

He notices none of this, of course, and happily rambles on about what he learned in class. He really is oblivious sometimes, because to Beca it is painfully obvious that Stephanie is interested in him. She's tried to tell him before, but he just laughs it off.

He starts talking to Stephanie more, on the phone, via text messaging, and then he starts talking about her. They'll be watching a movie and he'll interject what Stephanie thinks about the acting or the music. They'll be eating dinner and he'll repeat a funny story that Stephanie told him after class.

She tells herself that it's no different than her telling him stories about the Bellas, or him talking about Benji. But it is different, because she can't shake the feeling that Stephanie wants to be more than friends with her boyfriend.

They have a big blowout over it, which results in her storming out and him chasing after her, and hot make up sex in the end. But the feeling won't leave the pit of her stomach, that gnawing feeling that she can't seem to shake.

After the fight, she notices a change in him. He's more considerate of how she feels. Only now, he hangs up his phone call with Stephanie when he arrives at her dorm room for the night. And he doesn't react to her texts. Instead, when his phone buzzes with a message and she asks who it's from, he says, "No one important," which always means Stephanie.

She thinks Stephanie is all in the past. Only, the following semester, she turns up in one of his classes again. Beca sees them leaving together one day and asks him about it.

"She's the same major as me," he explains, "So we're probably going to run into each other."

Beca doesn't say anything. She's tired of having this fight with him. She trusts Jesse, she really does, and she knows he would never cheat on her. And still, she doesn't want Jesse around Stephanie. She doesn't want him to even look at her.

She tries, she really does, to be the supportive girlfriend. She's kind and smiling when she sees Stephanie or Jesse talks about her. She's not going to be that girl, the jealous kind who makes unfair demands because she's too insecure to trust her man. No, she's not that girl.

They're settled on her bed one night about to watch Silver Linings Playbook when he says, "Steph said this was really good."

"Great," Beca replies, unable to hide the sarcasm in her voice.

"What?" he asks.

"Nothing," she says, "Let's just watch the movie."

"Bec—"

She stands up abruptly, almost knocking his laptop off the bed. "I hate this!" she throws her hands up, starting to pace around the room.

He scoots to the edge of the bed, about to say something when she cuts him off yet again, "It's like the universe keeps throwing it in my face! And I'm like shut the fuck up and it's like, no! Here's reason five million and two why you're not the one for Jesse!"

"Who is saying we're not right for each other?" he asks hesitantly.

"Don't you see it? Stephanie. She's the movie lover. She laughs at your jokes. She's beautiful, and unbroken, and normal, and affectionate, and everything I'm not. I bet your mom would just love it if you brought her home next summer instead of me! She'd actually let you kiss her in public!"

"For the billionth time, I do not want to be with Stephanie!" he exclaims.

"I hate that you're friends with her. I hate that she makes you laugh and smile. You're my best friend, Jesse. You're my everything! And I'm sorry, but I just don't want to share you," she continues to pace.

"I don't want to share you, either," he says quietly.

"See, that's the thing, you don't have to," she corrects. "I'm not that close with anyone else here, or anyone else in my life for that matter. I'm all yours."

He freezes, as if this never occurred to him before. He's the social one in this relationship, but she isn't. Sure, she's friends with the Bellas but she hasn't opened up to them like she has to him. She isn't close with her family like he is either.

"I'm sorry," he whispers, unsure of what else to say.

"It isn't your fault, it's mine. I'm alone because of me," she sits down on the bed next to him.

"No, it isn't," he replies, "I know you. You'd rather have one best friend than a hundred acquaintances. You're all about quality rather than quantity, and I respect that. I didn't realize that my friendship with Stephanie was hurting you like this. I'll back off, tell her I'm too busy to talk, stuff like that.

"She's going to know it's because of me," Beca says, putting her face in her hands.

"So what?" he says. "Oh, and by the way, my mom loves you."

"She does not!"

"Yes, she does. She told me so just last week. Remember when you came into my room and I was on the phone? She said she knew you were there because my voice sounded happier as soon as I saw you. She said you're a keeper."

Beca laughs, "Well, good."

Jesse keeps his word, he slowly severs ties with Stephanie. They are still in the same class, but he no longer walks out with her. Beca is waiting for him one day as the class lets out, and sees him walking alone, Stephanie about fifteen feet behind him.

"Hey weirdo!" Beca calls, before running to him and kissing him soundly on the lips. He's shocked at first, being that they're in the middle of a crowd of people. She holds him close, kissing him for a long moment before finally breaking apart.

"Beca," he breathes, "What was that for? I thought you didn't do PDA."

"Maybe I want the whole world to know you're mine," she looks directly in his eyes.

"I thought it was fairly obvious," he replies.

And he doesn't give her another reason to be jealous, not for a long, long time. Around eight years later, a very bored and very anxious Beca is sitting on their sofa in their Los Angeles home one evening.

"Ugh! Why won't you just die already!" she yells, flinging popcorn at her television screen.

Melody is sleeping upstairs as she watches the popular premium cable channel show.

"Come on one of you vampires, rip her fucking head off!" more popcorn flies at the television, smacking the blonde actress square in the face just as Jesse walks into the room.

"Hey come on, not the new flat screen!" he jokes, noticing that the actress she despises is on the screen.

"I hate her!" she says emphatically.

"Do you hate her or her character?" he asks.

"Both!" she exclaims, and he laughs.

"You know, you should feel sorry for her, she's only some B-list actress who's stuck on the TV track," he interjects. "Why don't you just change the channel if you're so frustrated?"

She turns the channel, and on comes some awards show, the same blonde actress appearing on the screen. "God damn it!" more popcorn flies, "Who does she think she is in that dress? It looks like slutty cellophane! And isn't she like, thirty? Teen Choice doesn't mean you have to show up looking like one! And there's her hot-ass younger boy-toy marriage home-wrecker boyfriend. They make me want to projectile vomit all over the TV!"

He's laughing outright at her now. "What is it about her that you hate so much, Becs?"

And then it dawns on her, this actress reminds her of Stephanie. "Ok, well maybe she reminds me of Stephanie from college. And maybe, I just don't like her with him. You're way more attractive than him, Jesse Swanson. Because it's your personality, it's who you are, your true character, that makes you hot."

"Oh, I'm hot now am I?" he teases.

"Come on, you know you are," she rolls her eyes.

"Prove it," he says, his voice low and husky.

Not breaking eye contact with him, she switches the television off with the remote. She walks over to him slowly, placing her hands on his chest as she tilts up her face to his. "Come on nerd," she whispers in the tone that drives him wild, "Show me some of your moves, the ones that drive all the girls crazy."

He shakes his hips a bit, running his hand around his head through his hair, and down the side of his neck and chest, the trademark Jesse Swanson dance move that she mocked in college. In response, she points at him and turns her hand into the shape of a phone, holding it up to her ears as if to say "Call me." He laughs, moving in to nibble her earlobe.

"Want to start on making aca-baby number two?" she whispers into his neck, and he stills, turning to look at her.

"I don't know," he says, "That will require a lot of sex. And it's more procreational than recreational."

"You make it sound so clinical. Not up for it?" she smiles, tugging at the hem of his shirt.

"I don't know," he grins, "I left my lab coat at work."

She shakes her head, "You are such a dork."

"It's one of the main reasons you love me," he retorts, and she laughs into his lips, kissing him soundly as he lifts her bridal style and heads towards the stairs.

And as he makes love to her over and over again for the next few days, she forgets about the B-list celebrities that kind of resemble Stephanie and Jesse, because she knows that Beca Mitchell-now-Swanson, was meant to be with Jesse Swanson like this, and nothing else matters.
