I'm plagued by the thunderbolts, have some randomly assorted headcanons
Ava, Bob, and Yelena yell cucumber instead of "bless you". They especially like yelling it at John because he finds it dumb and annoying. Bucky and Alexei are confused.
Ava and Yelena end up getting really close. Neither of them have had friends since childhood, so it's nice to connect with one another. They bully John together 💕
John gets his kid for the weekend. While he was a distracted father, he still knows HOW to take care of a kid. None of the others besides Alexei do and he can't believe how incompetent they are. Alexei likes John's kid because toddlers are easy to impress lmao.
You know the "life changing field trip with Zuko" thing from ATLA? Life changing field trip with Bucky. One way or another, Bucky either comes to an understanding or gets closer to the others on the team. Bob was thoroughly startled to find out that Bucky wasn't scary, just socially awkward
No one but John and Bucky knows how to cook. They don't even cook WELL, just passable. How everyone else has made it this far on take out and frozen meals is beyond them. Ava and Yelena go "how hard can it be?" And now they're yelling at Alexei to follow the recipe as he insists that he knows better and this will taste WAY better. Bob is quietly ordering pizza.
If things turn into a genuine screaming match on the team, Bob going "can we please calm down?" Makes everyone very bitterly simmer down because they know this a bit triggering for Bob
In general, I think they start to learn one anothers triggers and start being more mindful of them. Barely even consciously, but they've all felt that void inside them and don't like being the reason someone else feels it again.
Everyday Bob is blown away by what's happening around him and what's happened to these people. Like, while Bob had a rough life, it was a "normal" kind of rough. No experimentation, no super powers, no government plots. Just a normal guy dealt a terrible deck in life. He's spent the vast majority of his life with no powers.
Ava, Yelena and Bob decide to hang out one day as normal people. They are very bad at this and they come home with torn clothes and a cat.
I'll stop yapping for now, I just love them
