Imagine . . .
Attending the Stark Expo with Bucky and wandering off with Steve.
Bucky's heavenly blue eyes eagerly gazed at the show in fascination. An interesting detail about the car on display sparked a thought in his mind, and who else better to tell than his little sister? He turned around, only to see that not only did you disappear but so did his best bud, Steve.
"What the hell?" murmured the puzzled brother. "Where did they go?"
His eyes scanned the noisy arena, hoping that the idea in his mind wasn't true about where you and Steve were. A sigh of relief poured from his mouth when he finally spotted your figure, but you weren't alone. The other figure beside you was the one he didn't want next to you, it was Steve.
Bucky's chest tightened as he peered at the scene happening in front of him. Steve said something and you both started laughing, genuinely. It was a sight that Bucky never thought he would ever see. He has always wanted Steve to start dating girls, but not his little sister!
