Heller has a mind like Sherlock Holmes, he would never leave it that simple, he is the type of person who would want to ruin everyone dreams, ergo no one ever suspected red john would be mcallister .But here is the twist, episode nine jumps ahead two years, Lisbon rings Patrick up saying hes back red john was never killed hahahahahah it was like at the end of season three when we thought Patrick had killed red john but NO he only killed a follower, ergo mcallister is a follower. duh get the picture
