Lorelei said Red John and Patrick had shaken hands, also has the fact that the voice of Red John, I was thinking, many say it is Brett Partridge, however, I have another theory, could it be the Dr.Wagner? One who appears in the pilot imitating a crime of Red John? Think about it, he is a therapist, it is not difficult to manipulate people like Red John does, and also the fact that he has imitated a crime and not Red John was dead, and that Red John himself "not tolerate copies cheap ", following this direction, Dr. Wagner was to be killed for a crime copy of Red John, but not this, then, is that the killer is in our face since episode 1? Sorry for the bad english, I'm brazilian
