What if RJ is no one on the list of 7? What if PJ knows that and tries to not just kill RJ but defeat him all the way from the basis to the top. He wants to crush him by revealing the whole tyger-tyger-organisation and its wirepuller RJ who blackmailed cops, judges and other people so they work for him. These people even don't know that he's a serial killer. Even Smith said that you get a phone call and asked to do something and you do it unqestioningly. He also mentioned that the tyger-tyger organisation is aware of it that RJ is a member too.

He also set a trap by saying that Bertram is RJ. The real RJ would never ever accept it that some other guy is getting famous with HIS work.

Besides we know that he doesnt want to kill PJ, he wants to play a game with him. Wouldnt he protect PJ when Bertram was about to kill him? The only person who got in the way was Lisbon (hint?). Or wouldnt he care if some random guy killed his "lifelong" friend PJ?

We also don't know what happend in the house. "Wait, no!".. who said this and why? I hope we get an answer next week.
