Now since we all know that red john is Thomas McAllister. abut i think that wayne could be red john now because thomas was trying to tell patrick who told him the seven people on the list. Now ive been watching this show since the start and red john is too smart to go out in the open like what McAllister did. it seems like an important subject and could be someone from the cbi group. wayne was helping out he fbi agent on where jane might be and was calling the fbi officer sir. he could just have been helping red john but it would be a very good ending if jane caught out wayne and he put on the voice and said he was red john. this is only a theory i came up with not sure if it is plausible.
