I also think that Bret Partridge is RJ. He was in the first episode and also in the final episode of Season 5. Many other people have listed why he fits the physical and age profile of RJ. It's interesting that he appears at the beginning of 'Red John Rules', and is the last named suspect of the 7. I also suspect that PJ has set a trap for RJ with a fake list, apparently stolen by RJ, since some of the names are ridiculous (Bertram, Sheriff McAllister, Smith), but there is an apparent connection with Red Stiles who seems to know who RJ is. Also, his creator, Bruno Heller has said that many people will be disappointed when they find out RJ's identity, and BP is the #1 suspect, so that would indeed be disappointing. The video of Lorelei may have been edited down to Patrick's final 7 list. RJ wants PJ to think he has psychic powers to read his mind. It is possible that PJ's father is still alive and told someone close to RJ about Patrick's childhood.
