Here he was. Again. Another Friday night where all the Avengers were having a celebration over a victory and Bucky told Steve he was passing on the festivities. Sure, he didn't think going would be bad. He'd have poked fun a little at Sam for whatever reason he could find, maybe talk to Wanda a little about things going on in their lives, shared a drink with his best friend the hero - but no.
No, instead, Bucky was climbing up the fire escape to a certain young hero's apartment window. It was a little ridiculous - the former assassin even calling himself stupid halfway up - but his limbs weren't stopping until he hit the top where he knocked on the closed window.
He glanced back at the city, taking a breath while he took in the sight as he waited patiently.
