People are asking why RJ didn't kill Lisbon and speculating that it's because he likes her. Well, Walter Mashburn likes her also, plus, he's always looking for thrills that money just can't buy, and if he's a sociopath (and many big businessmen are), he might be cold enough to get his kicks killing and playing crazy games. Plus, he was wearing a red sweater when he came to visit Teresa at the office, like, hey, look, red! Hint, hint, let's play cat amdn mouse some more !

I don't really subscribe to this, actually, but I do think that PJ did fake up the suspects board, because he knew RJ's cronies, and maybe others, would break in and video it, etc. He knew that RJ would figure out who his suspects were, from how he (PJ) assembled the clues. He knows that RJ is watching him and so he, PJ, has to act as if he himself believes the list of suspects is real. I don't think PJ beleives any of the people on the list are suspects, but he needs RJ to think he does, so that RJ feels secure enough to let down his guard, thinking PJ is off in other directions.

Plus no way RJ would have gone to a shrink and told her the truth about any of his phobias, it was jus a ruse to check out what she knew about PJ.

And again, if RJ is watching PJ, he may find out that PJ has found the tape of RJ's visit to Sophie -- one way would be to see if PJ was testing his (phoney) suspects out for a phobia.
