Okay but imagine Bucky Barnes still being confused and regaining his memories while living in the tower, he still sleeps with a gun next to him, he thinks of Steve as his handler and expects him to punish him when he does something wrong, he’s still in assassin mode 90% of the time and rarely talks.
But one day he’s drinking milk or something and he gets some really bad hiccups and just puts his head down on the table and suffers through it while Steve’s just rubbing his back and some of the other team members walk by and are a little shocked because here’s this 90-some-year-old ex-assassin who everyone (except for Steve and maybe Natasha) is intimidated by and he doesn’t know how to deal with the hiccups.
Steve stays with him until they die down, and Bucky’s groaning in frustration because they won’t stop.
“Steve—hic—they hurt now,”
“I know, Buck, I know,”
“Is this supposed—hic—to happen?”
“When was the last time you had the hiccups?”
“I couldn’t remember my own—hic—name, Steve—hic—what makes you think I could—hic—remember a detail like that?”
