This is EXACTLY why Bucky Barnes is my favorite character and it brings me so much joy to finally see a little bit of it on screen.
I feel like an extremely minor 616!Bucky moment that really sums up who Bucky is as a character is when he and Natasha are strolling in the rain and he begins to whine about it and she’s like “...seriously? That’s too much for you? You fought Nazis.” and he just straight up says “If I have to compare everything to fighting Nazis, I’ll never get to complain about anything.” and I remember stopping and smiling because that’s it. Bucky hits every trope of the grimdark hero but instead of becoming the grimdark hero he just... complains a lot about inconsequential things in ways that hurt no one. He remains sweet and genuinely upbeat as a rule, he’s just... gonna make sure the world knows when he’s Mildly Inconvenienced. He’s 100% on board with helping you move on a weekend! He’s just gonna complain about random stuff while he does it and he won’t expect you to understand half of what he’s even talking about, he just has a complaining quota to meet, like a psychological fitbit that measures harmless irritation
