MJ’s older sister, Brielle Ivy Jones, has never been one to chase the spotlight, she likes quiet, calm, being inside, mainly because the woman has crippling social anxiety. With her easy style, warm presence, and quiet strength, Brielle carries herself differently, definitely a lot different from the Avengers, but ah, of course, her little sister had to date one. But Bri loves Peter. Most nights, someone could find the three on the couch in Brielle’s apartment, a glass of wine in Bri’s hand, the couple cuddled together on the end. They have shows the watch, only together, have Pizza nights, all that jazz. And Bri adores Peter, because he takes care of MJ, and he loves her unconditionally, and that’s all Bri could ask for. And Peter knows Bri doesn’t like large crowds, or big affairs, or having to talk when she doesn’t want to, so he doesn’t push. But when Peter insists on dragging MJ and Brielle along for a “fun day” or something along those lines, at the Avengers Tower, his way of showing off his girlfriend and honorary “sister-in-law”, Brielle humors him, though Brielle really doesn’t want to be there. She doesn’t have a problem with any of them, but they’re loud, and Brielle really doesn’t know how to feel about that, and she’s hardly dazzled by the flashy tech or Tony Stark’s larger-than-life personality. From the moment Brielle stepped into that Tower, Bucky Barnes notices the subtle things, the way she’s looking around the room for quiet, the way her laugh (probably at Peter) sounds like a soft anchor in a noisy room, the way she doesn’t take a second glance at Tony without asking a stupid question, and the way she talks, quiet, sweet, gentle. He just stares, only lets his gaze linger when he thinks no one notices, Peter’s shown him pictures of Brielle, well, not him alone, but he’s shown the team. He says a few words, mutters behind her back to himself, but doesn’t make conversation, yet she keeps showing up, or appears when he least expects. And the shell finally cracks. Whether it’s tagging along with MJ and Peter or dropping by with coffee for the girls, Brielle’s presence becomes familiar. Natasha, Pepper, and Wanda admire the way Bri holds herself, teasing quietly about how Bri’s the first person to catch Bucky’s attention without even trying. Steve and Sam eventually grow tired of the silent staring, pushing Bucky to take the first step. What follows is a slow burn, stolen glances turning into brief conversations, brief conversations into late-night talks in the quiet corners of the Tower or through the phone. Bri isn’t scared by his past or his reputation; she’s only interested in the man in front of her. And for Bucky, that makes all the difference.
