Well, that was something!
Michael Emerson and Jorge Garcia showed up as special guests, that was fun.
They showed a few old scenes, most notably the scene from The Constant where Desmond calls Penny..Imagine seeing that in a movie theater!
Also, at the end we were treated with a scene from the finale. It didn't spoil MUCH but it answered a LOT of questions. Do you guys want a summary of the scene they showed? (Damon and Carlton said they specifically chose this scene because they felt it was okay to see)
