"D.O.C." is the name of tonight's episode, and I am really looking forward to it. Previews seem to indicate some good stuff is coming.

At EW.com, these comments intrigued me:

"Tonight, we will make a return visit to the Medical Hatch, and discover a secret room that Kate and Claire missed on their last visit."

"Jin will do kung fu on someone you thought was dead, but is very much alive."

"The very last scene of the episode, you're going to hear something that makes your head spin."

"Sun discovers the identity of her unborn child's father after being examined by Juliet. Meanwhile, Desmond allows an unlikely foe to help save the life of a mysterious new island inhabitant."
