- RJ made Lorelei read out a large list of possible suspects when he knew about her telling PJ about the handshake thing.
- Then after breaking into PJ room he could see how was PJ thinking and he his likely to suspect 7 people (He didn't find names, only hints/clues that point to 7 people)
- So according to the data he gathered, he made a list of his own 7 names that PJ likely to suspect, including his own name and edited the video to match the list.
- When PJ first watched the video without Lisbon, he found that some the suspects Lorelei read out were wrong, so we now have 2 lists (one by RJ, one by PJ).
- The true suspects are the mutual ones in both lists, and PJ is keeping that for himself. Before letting Lisbon watch the video, he faked that the list made by RJ is identical to his list, in order to let RJ think he's one step ahead when he actually "two steps behind", just like he faked his breakdown in season 4.
- Also, RJ and PJ knew each other long before PJ's family was murdered that's why he knew about his memories. But why PJ can't recognize him then ? simply because he had a surgery to change his face, that's why he asked (then killed) Jason Lennon.
- Remember "he is mar" ? (mar = injury, defect, etc). Jared Renfrew did know about RJ's injury, but this information was outdated because it happened during the murder of Carter Peak and he could have had the surgery anytime later on. (Probably long before the murder of PJ's family).
I know such scenario could be far fetched, I just wanted to share my thoughts.
