I'm sure enough time has passed to make his change realistic.
The issue is do we know how much time has passed?
There's an issue with the writing and pacing if people have to ask, "how long has he been in there?"
Can't one character say something about it? Why can't Stone say, "I just want to get the kid out. He's been in there for months."
Or why couldn't the first guy needing a cell phone step up to him and say, "You stupid bitch. Three months in this place and you still ain't learned a thing?"
Instead you get Omar (sorry he's always Omar) saying, "I'll make you a legit prisoner in no time."
Well, damn, that's confusing. Why would someone say that 3 months later? Can Naz be that dumb as to how things work in the system to not understand that people make money off renting out burners? What exactly has he been doing then?
But I'm not trying to poke holes in the story. Not the intent of my post. I'm only a bit underwhelmed with the direction of the show and expressing it. I still like it and I don't say it to change anyone's mind on it.
