Just a couple of notes.

1) The CBS Mentalist site now has two previews on it. 

2) One of the previews specifically says that RJ brought the bomb to the meeting to kill Patrick and the others.  This is a blow to those who say that RJ can't be on the list because why would he come to the meeting.  The answer is that RJ didn't get the memo that there are two more weeks until he is unmasked and planned to end it on Sunday.

3) I honestly believe you have to get it out of your heads that BH is going to pull a head fake.

If it's Partridge or the Michael/Bob Kirkland twin thing then it's just a stupid ending that is so cliche.

4) I am still betting on McCallister since he was the first suspect we saw.
