*** SPOILER ALERT**** outcome of Roddy's exit

Um, I saw this just recently for the first time but I noticed after ***SPOILER ALERT*** that there is no follow-up to Roddy's teacher getting blown up in his car wreck (?!) Or did I miss something. IF you ask me that would've been far more convincing for a 'payback' before the gang attacks Perry King's wife (well that's even more for payback trust me; but you get the gist since the teachers were friends and King even tries to help Roddy after his meltdown in class w/a handgun)

Anyone? Thank you in advance
