terry o'quinn and michael emerson teases of finale season5

The dead will walk again in Lost's two-hour season finale on May 13. Michael Emerson, who plays Ben Linus, tells me, “We see some people from the past. It keeps us speculating why certain people seem to be holding on and revisiting the living in some interesting ways.”

Terry O’Quinn--whose John Locke is one of the undead, says the finale will help explain why John, as well as Jack’s father, Christian, came back to life on the island. “Someone thought they’d be useful,” teases O’Quinn. “Someone is using Locke to their ends.”

So who do you think might be making a return appearance in the finale? Claire? Charlie? Charlotte? (What’s with all these C characters anyway?) And if Charles Widmore is Daniel’s father, who else might he have fathered on the island? Might Charlie and Charlotte have both been named after him?
