Sam drags himself into the apartment, every single muscle screaming in pain like he hasn't felt since boot camp years ago.

Bucky, the chipper asshole, claps him on the shoulder and doesn't even look remotely like he's been at the gym for the past four hours. "Spar again tomorrow?"

Sam glares at him with every ounce of irritation he can muster. "I'm gonna go get blitzed on ibuprofen, sit in the bath for two hours, and then tomorrow, I'm gonna kick your ass."
