After watching "Strawberries and Cream" again, I know it's Gale Bertram. In an earlier episode, Jane talked about the power of suggestion. In "Strawberries and Cream," Jane suspected Bertram of working for RJ, for the 2nd time. It wasn't until Bertram said, "You're at the end of your rope..." to PJ that Jane immediately thought of O'Laughlin instead. He put that suggestion in PJ's mind. Then, he walked away right as the fake RJ gave himself away. I think O'Laughlin was part of Tyger Tyger, doing Bertram's bidding, and fake RJ (Carter?) was also a disciple willing to take the fall. One very interesting thing about the episode that I just can't get over is when LaRoche kills the gas station attendant. He looks at Jane and says, "He tried to escape. He was going for a gun. I had no choice." Seems almost word for word what Reede Smith told the patty wagon driver about Kirkland. So either LaRoche is also Tyger Tyger, or Tyger Tyger really are trigger words for hypnosis. LaRoche almost says it in a rehearsed way. PJ suspected something about Bertram twice in the same season. He suspected he worked for RJ, when in fact he IS RJ!
