A concept: Tony starts talking to himself. It’s not unusual except for that it is. All he does is repeat himself. “Hello ladies. I’m fine. How are you?” Over and over and over. He says it to himself over breakfast. He says it to himself in the mirror. He says it to himself as he brushes his teeth. He mumbles it to himself during debriefs. The Avengers are… really starting to worry him, honestly.
And then they’re on their ways out for the day, different plans that they’re all doing but happening to leave at the same time. Tony is leading the way because he’s late for a meeting, as usual, when they’re accosted by a bunch of little girls wearing brown vests and skirts and wearing cute little berets. “Hi, Mr. Stark!” they exclaim happily. “How are y–”
“THIN MINTS,” Tony blurts out, and then crumples to the ground on his hands and knees in despair. The Avengers stare.
“It’s alright, Mr. Stark,” one of the little girls says consolingly as she pats him on the head. Several of the other Girl Scouts are packing up a fabric shopping bag full of Thin Mints. “There’s always next year.”
