Phil and Thor hang out and swap battle stories
It's really hard to convince Thor that Phil isn't some sort of demi-god after he turns out to not be dead after the Loki attack. Thor insists that the Son of Coul come out for drinks with him once he's out of hospital and medically permitted to return to regular duties. Fury is making him take all of his piled-up vacation days, though, and he doesn't have a lot to do.
So he agrees to have a few with Thor, and everyone else comes with them. By the end of the night, Bruce has been long gone, presumably go to meditate or something, and nearly everyone else is in various stages of drunkenness or unconsciousness around the living room. Natasha is leaning on the arm of the chair, attempting to listen raptly while Thor regales Phil with stories of his conquests before he came to Midgard.
Since Phil can't keep up with Thor beer-for-beer, he keeps up with him story-for-story. Most of his are incredibly vague because no one else has high enough clearance for the unaltered versions, but apparently it's still good enough for Thor.
He tells Thor about Budapest, and Natasha giggles. "That's not how I remember Budapest."
Phil spares her a glance. "I'm pretty sure both you and Barton were too busy recovering from severe alcohol poisoning to remember much of Budapest."
