I think the fact that Jane asking for a trailer as one of his demands proves a few cool things.
1: Jane most likely knew the fbi would reach out to him making this idea he "moved on" silly.
2: Jane when he receives the trailer will no doubt give it to his carnie friends who were sending lisbon letters for him.
I think the key to catching red john is in janes carnie past and whenever that episode happens its gonna be great.

Also the fbi is the belly of the beast. Jane knows red john had people in the fbi. jane is in the belly of the beast for very good reason. He wanted the fbi to shut down the cbi and its all working great.
Macalister was NOT RED JOHN! He may of used red johns persona but he is not the real deal.

Also, the scene where lisbon and rigsby fake their deaths and jane meets red john was a huge clue.
Mr jane always asks me how can rigsby be red john if he was with the team when it all went down. Well rigsby may be a follower or used a voice recording for that scene . IF THE HOME ALONE KID CAN DUPE ROBBERS WITH A RECORDING RED JOHN CAN!!!!! Remember the talkboy? Lol

Anyway Rigsby went out shadily for nachos right before the meeting . Could he of warned red john or set that bike up for jane? Like i said before the bike had a toe tag on it , the same found on fake rigsbys toe in the morgue.
How the hell did RJ steal Wayneright ? He was at cbi?
Cbi ron maybe.
