That was a really solid episode.
Great opening sequence which solidifies my theory that the killer is an ewok.
Really great ending with an awesome kill that will finally get things rolling as we now have a public murder (and of one of the primary suspects to boot).
And we finally get acknowledgment from the characters that weird shit is going down, including mention of the missing Lucy (although they did kind of gloss over that), and the discovery of the Reverend's awesomely mutilated body.
Booth is definitely dead, as it appears Malcolm buried him. However, now it really makes that whole plot thread feel even more pointless, as it seems to be pretty much resolved. Same with Trish's discovery of her stepmother's infidelity with her brother-in-law. You can almost skip the previous episode and not really miss anything.
Another booby-trap kill, so no one new is exonerated, but an argument could be made to exonerate Shane, as the sheriff said he is in jail and will remain there until after the wedding. However, until we get a another "hands on" murder, he's still a suspect.
I like the idea that someone (presumably the killer) is fucking with people, from the running shower in Malcolm's room, to the (presumably) planted firecracker in the church to implicate J.D. Someone is watching them all very closely.
I think creepy, half-burned woodsman is a complete red herring. He's definitely not John Wakefield. I went back and checked against the photos of Wakefield they showed earlier.
Shane's ominous "I have one more surprise for you" statement is also a red herring. As Henry seemed quite cheerful shortly afterwards, and we see J.D. is quite prevalent in the upcoming episodes, it couldn't have been anything too dramatic. He probably gave Henry his wedding gift or something.
It kind of sucks that after the first really good, cliffhanger-y episode, CBS is making us wait two weeks until the next one so they can give us a very special episode of The Mentalist next Saturday.
