The kids and I were hoping against hope that Charlie wasn't really dead. When we saw his flash up briefly in the teaser ads, we thought, "All Right!".
Well, okay, he really is dead, and is now just part of Hurley's vivid imagination. But is was nice to see Dominic Monaghan come back at least one last time (although he could show up again anytime. A lot of other dead characters have popped up in flashbacks over the past seasons.
And I see that Harold Perrineau (Michael) is listed in the main cast credits again. We haven't seen him for almost 2 years (or about 30 days), since he left with Walt. His character left as a traitor and murderer, so I wonder how he is brought back.
Only 8 episodes this year, and one down already. It's going to be a tough season....
