They're all standing in a loosely scattered group, Shuri between him and T'Challa talking a mile a minute, Nakia saying something to Okoye and Steve having cornered Ayo for an earnest conversation that Bucky's pretty sure he doesn't want to hear, when he hears Sharon's voice and looks up.

An instant later, he's forgotten everything else.

Red, his brain informs him, stunned and scrambling for coherent thought. Pretty.

Only 'pretty' isn't enough. She's gorgeous, absolutely incredible, all long legs and a waterfall of golden hair and laughter in her bright eyes, and that red dress that clings to her like a silken second skin, and it's about at that point that he realizes he's stopped breathing and yet he still can't do anything but stare.
