I think Bobby Elvis will go tell the truth about Louanne and since Otto won't sign any transcripts he won't end up ratting on him.
Hopefully Clay kills Tara, but I'm sure Gemma will bust into her hospital room or something and stop it.
I'm not sure about Opie, I don't think he'd listen to Unser if he tried to stop him at this point.
Poor Lenny Johnson (Kozik), the creators killed him off in The Shield and this show. Poor guy got blown up in both shows too.
