Lost: Who's your daddy?

Spoilers for last night's "Lost" coming up just as soon as I apologize for using the tritest subject line possible...

Who woulda thunk it? Nearly three years in, and there's still the occasional surprise to be found in a flashback for one of the original characters. Until now, we thought that Jin became a legbreaker as a misguided way to provide for Sun; now we know that he was unknowingly paying off a debt Sun owed to her father. Puts a whole new spin on much of what we know about these two, without rendering invalid anything that came before. Plus, we got the usual sterling performances by the underused Daniel Dae Kim (now with spin kicks!) and Yunjin Kim (who, like Elizabeth Mitchell, could stand a sandwich).

In the present day, we have a bunch of mind-bending stuff, from the magically resurrecting Mikahil (are we sure his last name's not Rasputin?) to Parachute Lady's assertion that the wreck of Oceanic 815 was found, with no survivors. So which of the pre-existing Grand Unified Theories of "Lost" does that news fit into? Purgatory? Dream? Is the Dharma Initiative so powerful they could fake both the crashed plan and corpses of the passengers? And how did Bakunin survive the Sonic Wall of Death? Is there more than one of him? Are the island's healing powers so potent that Nikki and Paulo aren't the only people who were buried alive?

As for Juliet, the writers are trying to ride the knife edge with where her loyalties lie. She's still feeding intel to Ben, but she hates him. Question: with the sub and the communications station both blown up real good, what the hell could he be promising her? And should I care?

All in all, pretty good teevee. What did everybody else think?
