I've been watching important old episodes to see if i could figure something out about Red John's identity. When i watched the finale of season 3, I unfortunately found out while watching that episode that or PJ's list is a trick of PJ(even though Brunno Heller told us we could trust the list) or Brunno Heller (BH from now on) messed up. This is because PJ should have eliminated Bertram from his list and he didn't.
Firstly i will have to give you a short recap of the season 3 finale to explain what BH did wrong. So in the finale PJ knows there is a moll in the CBI working for RJ, the moll is one of 5 people including Bertram and Craigh O'Loughlin (COL from now on). RJ wants to kill Hightower. PJ figures a trick. He tells all the suspects where Hightower is supposed to be, so the moll will tell RJ where Hightower is and he will send an assasin to her place. The trick is that all the suspects are given a different location but all hotelrooms directly above eachother. The assasin enters the room PJ told Bertram about, but later they found out the assasin was planning to use a rope to get one floor down to enter the room given to COL, thus proving COL is the moll. COL gets killed and Lisbon calls the last person COL called which is the RJ-imposer, whom PJ kills later.
This proves COL is definitely an RJ disciple, just like the RJ-imposer. Also RJ failed for the trick of PJ. But if Bertram were RJ then he would have known PJ gave a different address to COL, then he wouldn't fall for the trick and wouldn't send an assasin to Hightower's assumed location. PJ should have been able to deduce this yet Bertram is on PJ's list, therefore my conclusion is:
BH made a mistake or PJ is using the list for some kind of trick (but even then somebody of PJ's team could have figured out why Bertram can't be RJ).
