I like that they're not shying away from negative consequences of that battle. And for someone like Tony, it makes sense to suffer from PTSD after something like this.
He's no soldier after all.
Cap fought on the frontlines in WW II. Widow and Hawkeye fought in modern battles (judging from the Budapest footage or whatever that was).
Thor? Please, he's seen thousands
of battles over the eons.
They're all used to this shit as opposed to Tony.
I'm excluding Banner here since, technically, he didn't fight.
