Michael was on about a month ago, when Hugo was talking to him in the jungle. I was surprised though that they never brought Walt back at all. They even brought Shannon & Boone back Anybody else notice the stained glass window in the back room of the church at the end? There was also a menorah on a shelf, & a picture of one of the Hindu gods on the wall **Edit.... They mentioned several times how much Walt has grown in real life, & alluded to the fact that this was why he was "rafted" off the island, & not in the final episode. He was 11 when the show started, playing an 8 year old
