He is, hands down, my favorite guest star. Hands down. He's so awesome. And he ended the episode before last PERFECTLY! "Got any milk?" I was laid out. Here's what JGM said about Gale:

"Henry's true identity is going to be the topic of a lot of contention on the show. We plan on heaping twist upon twist upon twist with that! Henry is a character that the fans are going to have to watch very closely, because he carries great meaning for the future of Lost and the castaways in general. On the island, his ultimate faith is going to affect everyone on the show."
