You called it lol
GOTG literaly is about trauma and you can see the different way people deal with trauma. Quill couldn't cope with the seriousness of his trauma, so now he takes nothing serious. Gamora channels hers and is goal oriented. Only focused on the task at hand. Rocket lashes out and pushes everyone away(Except groot). Hide behind sarcasm and insults. Drax internalizes everything and was suicidal. One my favorite scenes is from GOTG 2 where mantis touches drax. Drax looks fine on the outside, but when she feels what he's feeling she breaks down immediately. A great subtle scene to give us a glimpse inside drax. We also see the scars of Rockets trauma. When he takes his shirt off and talks about how they Tore him apart and put him back together again or whatever the exact quote was. He's covered in scars and cybernetic implants. There's a reason GOTG got so much praise is a comedy that know when to get dark. Guns a good writer
