Ship: Steve Rogers x Peggy Carter (also TonySteve if you squint)
The picture was of Tony, around age five, leaning over precociously to kiss an older woman on the cheek. Her face was mostly obscured by a mass of brown curls as she turned away from the boy, but she appeared to be laughing.
"Hey Tony, who's that?" Steve asked.
"Hmm? Oh, that's my Aunt Peggy," he replied after a moment of casual observation. "Not an aunt really, she was an old friend of my dad's. Wonderful woman, she uh, she used to work with him back in World War…"
Steve had gone very still. Tony closed his eyes and berated himself soundly for shooting off his mouth before thinking. When he looked again, Steve's eyes were trained on the picture with such complete heartbreak he looked almost calm, and one finger rested gently on the edge of Peggy's smile.
"Hey man," Tony sighed as he sat heavily on the couch. "Sorry."
"No," Steve muttered. "It's alright."
He spent another moment staring at her, eyes flicking over every visible contour of her different but familiar face. Then he looked up at Tony with a small smile.
"So uh, were she and your dad – I mean, did they ever-"
"-have fondue?" Tony finished with a wicked grin.
Steve's dumbfounded look was excessively satisfying. Tony laughed and leaned back.
"No, they were just friends."
"Oh, well, uh. That's good, I guess." Steve's gaze wandered to the middle distance, and Tony could almost see the 1940's bunker he was remembering.
"You wanna know how I know about the fondue faux pas?" Tony asked after a moment.
"Not particularly." Steve's smile said otherwise.
"Well, I was talking about euphemisms one day - no real reason - and I asked Aunt Peggy if she knew what one was."
"Oh, no."
"Oh yes. Who would have thought that the first superhero knew so little about French cuisine?"
Steve had put his head in his hands by this point and was trying to hide his laughter.
Author's Note: Writing Tony's dialogue is so difficult for me! xD Please Let me know how I did/how I can improve on that.
