Peter’s fine. Really. Sure, his father ended up being a homicidal maniac who liked impaling him through the chest, he almost got everyone he cared about dead and succeeded with one, but really. He’s fine. Just don’t ask his team.
(More post-GOTG Vol. 2 fic except this one’s angstier because wow Peter watched two fathers die in his hands and I’m still mad about the Walkman.)
