Written for exchange on Tumblr
'Tony, what are you doing, exactly?' It's been a very, very long night in which everyone but Steve has got drunk off their asses. Clint and Natasha are sprawled on the couch, laughing their heads off about nothing, Bruce has snuck away in case of a other-guy emergency, Thor is attempting to beat Jarvis at a computer game, and here's Tony.
Wearing his costume.
The really skintight one that somehow got shrunk in the wash.
'Are you always like this when you're drunk?'
Tony answers by falling face first onto the carpet.
(The next day, the picture Steve took of it has gone viral.)
