"Lost": Who's the Daddy?

Warning: The remainder of this post contains details about last night's episode of "Lost"...

As "Lost" fans have long suspected, it was revealed last night that Jack's father, Christian, is indeed Claire's father--but she doesn't know that because she didn't even get his name.

Next week, we get the answer to another mystery as we find out why Locke was in a wheelchair. AND my sources say the episode on March 28th is going to be a doozy as we get the return of some old favorites (Hint: It's Paolo's and Nikki's flashback episode.) and a major twist that will have everyone buzzing (No, I have no idea what it is.)...

Thoughts?
