I am beyond pumped. I'm excited at the prospect that ANYONE who isn't dead could return (Tayvon, Rawling, Kavanaugh; it's a safe bet Antwon Mitchell will continue his recurring role). And what happens to the 3 leads (Vic, Shane, Aceveda) is anyone's bet. Shane seems like a near-lock to get killed (if he does, I'd bet on it being Ronnie who does it) but I'm not so sure. I see Aceveda either using the Cruz angle to get himself positioned as the next mayor or going down in flames with the Juan Lazano stuff bringing him down. Vic is equally likely to die, go to jail, just lose his badge or get away and continue being a cop. All the possibilities are amazing.
I'll say this though, if Vic is brought down and goes to jail, it'll be Wagenbach who gets him. If he dies, it'll be Terry's brother.
