Just finished watching the episode yesterday and would you believe it.................... I didn't like it. How is it possible for a pedophile to orchestrate such murders and kidnapping? Besides what did Ardiles ever do to him? Or JJ for the matter? The guy who came to shoot Rigsby was clearly not Haibach and the person who kidnapped Grace didn't look like his sister at all.............that figure was thin unlike his sister lol. Unless this show has given up on reasonable explanations............. it makes no sense that he'd wait 2 years to go after these guys again. 

Now that we've been disappointed yet again,what possible scenario will play out in the season finale?
4 possibilities are open to take place :-

1) Re-birth of Red John and his actual reveal

2) Lisbon and Jane do it on the couch in front of the FBI

3) Jane will wake up from his dream following the bomb blast at his house

4) Jane will wake up in a mental facility and notice that Lisbon and everyone else were just working there,his subconscious made them into police men lol.

5) The birth of the new super-villan i mentioned before............ Blue George.
