Tony notices AJ is up early and watching cartoons

IMO another hint at AJ's immaturity/age being the reason that Blanca broke up with him. He's depressed because he lost her and he's dealing with it by watching cartoons. He later goes to a therapist to deal with his relationship and there's this shot that appears to be an attempt to make him look small and childlike.

Tony tells Chris that he needs to get over his issues (which is very hypocritical of him)

Tony is the king of hypocrites. That scene reminded me of season 4 when Tony sees Furio has been crying and tells him he needs get over his father's death, then in the next scene he's in Melfi's office crying over Pie-O-My. Another example of his hypocrisy is in this episode when AJ storms out of the room and Tony says to Carm: "I feel bad for him, but what the fuck? Why's he gotta take it out on us?" If I tried to make a list of all the times Tony angrily takes shit out on other people/people that had nothing to do with whatever he happens to be mad at, I'd be done by the time this rewatch was over and there'd be noone left to read it..

AJ's buddies decide to go rough up the debtor they threatened. AJ tries to opt out but he's pressured into joining the guys.

When Tony and Carm are arguing about AJ going to the strip club, he says "believe me, this is the way--and the way back to college.." I think what he means is this is the way to get him out of his depression. The weird (or maybe not so weird) thing is that Tony knows the kids that AJ's gonna be hanging out with are connected and involved in 'taking action on campus.' Wouldn't this be the same kind of thing Johnny Boy/Junior would be doing with Tony that leads him to the life? Is Tony encouraging this despite knowing the risks? Whatever the reason, it obviously works cause AJ seems to get hard as he watches the guy suffer. Maybe he does have he same sociopath genes in him that Tony does.
