the pilot set this up already. this kid's whole life is bad choices. couple that with the fact that he's in a scary ass environment and freddie was working him...it's a wrap. it does feel absurdly quick though for sure but i think naz just being a moron is pretty sufficient set up for the show.
It feels different to me.
In the pilot all of his bad decisions were either in a state of naive ignorance (following the girl, playing with the knife, stealing the cab) as he couldn't have known shit would've gone down THAT badly, and no normal person would; or in a moment of sheer panic, with split second decisions (taking the knife, forgetting the keys, running away, etc).
Stuff like the tattoos are just weird in the context of only a couple of weeks (at best) having gone by, because even in the prison climate, and even under pressure from Freddy, ha has to know how having a tattoo on your knuckles will reflect, it's not like he doesn't understand the concept, since the idea of looking presentable was introduced (with the clothing in court) and he still has the balls to refuse the clothing/gift from Freddy.
So to me that whole transformation is just way too accelerated, and especially if it serves the purpose of making him look guilty even when he's not, it's outright sloppy writing.
And one of the reasons i liked the pilot, was that it felt, overall, pretty damn natural in its unfolding.
I also didn't love too much the funerary home scene, i get what they were doing, giving you that Zodiac basement vibe, but it came off as somewhat comical to me, because it was so upfront and relentless.
Especially the line "That was no man, just a yarnball!", c'mon now.
