Couple of thoughts:

WALT is in on it. It may have something to do with a group of crazies kidnapping him, but I'm thinking that his sudden outburst of emotion (from the damn near autistically non-emotional WALT we saw last) was part of the rouse to completely get MICHAEL to do the work of Mrs. CLUE - since WALT gave MICHAEL pretty much everything he has wanted from WALT, "love" and the need for his father ("save me dad!").

As for CLUE's "has Walt ever been where he shouldnt be" - more psychic projection hints? The appearance of Kate's horse, Jacks father, Hurleys friend, drowning Walt, and the polar bear - all powers WALT possesses?

Also - appearantly Michael Emmerson will be a series regular next season.

Google him yourself if you want to know which character it is.
