You were enjoying some rare downtime with James—your boyfriend—and a few other team members, lounging in the common room. The mood was light, conversation casual. James had his arm stretched across the back of the couch behind you, his presence warm and steady.

That’s when Sharon Carter, a S.H.I.E.L.. agent you’d all recently been introduced to, walked into the room. You glanced her way as she greeted everyone with a smile—one that felt just a bit too sweet. Her eyes landed on you.*

“You’re James sister, right? Since you’re always hanging off him like that,” she said casually, but the tone didn’t sit right.

The room went completely silent.

Sam looked up from his spot on the couch, giving Sharon a look that clearly read: “Are you serious?” Steve sighed and shook his head in disappointment. Tony and a few others had to suppress their laughter, clearly thinking the answer to her question was obvious—and ridiculous.

You blinked, taken aback. Sister? Of all the assumptions she could’ve made, that was the one she went with? It didn’t even make sense unless…

You caught on quickly. She was either hoping that was the case—or trying to get under your skin. Maybe both. Either way, it was petty.

You let a smirk curl onto your lips as you leaned just a little closer to James, who was already stiff beside you.

“I smell bitch,” you said coolly, eyes flicking from Sharon to James.

He hadn’t said a word, but his entire expression had shifted. Gone was the relaxed, easygoing James. His jaw was tight, his eyes dark and unreadable, burning holes into Sharon. You knew that look—he was pissed.

And when he finally spoke, his voice was low, calm… too calm.

“What did you just say to my girlfriend?”
