Just a thought...tell me what you all think.
Jane always says Red John thinks of himself as an artist. We know his is also narcissistic. Brett Partridge is at all of the Red John and copycat Red John killing sites. Wouldn't it make sense for him to be there so he could "admire his work" and see other people's reactions? Not only that but he would be around Jane all the time. This way he can get a feel for how much he knows, and how close he is to discovering who he really is.
Let's just assume for the purpose of this argument that Partridge is Red John, and that he did fake his death. It looks like Bertrum, Smith and McAllister are part of this conspiracy. Also assuming that Red John is the leader of the group, it would have been simple for one of them to be in the house while Partridge appeared dead. Faking his death could be Partridge's way of trying to make other people look suspicious, and take some of the heat off of himself.
Heller said Red John killed Brett Partridge. Does this mean he literally killed him, or he killed the alias known as Brett Partridge?
