WHAT DO WE KNOW ABOUT MATTHEW ABADDON?
Thus far, Abaddon has helped assemble the team that came to the island from the freighter. He visited Hurley in the booby hatch to ask about the rest of the Oceanic 815 passengers. And he convinced a wheelchair-assisted Locke to go on a “walkabout” through the Australian Outback.

WHAT DOES HIS NAME MEAN?
Although Matthew means “a gift from God” in Hebrew, the Bible assigns Abaddon many not-so-cheery meanings, including “a place of destruction” and “the realm of the dead.” The word is also described as a creature that resembles a centaur with long hair, locusts’ wings and the tail of a scorpion. All in all, scholars have roughly interpreted all this to mean that he’s the king of hell, the anti-Christ, the big guy: Satan.

SO HE’S A BAD GUY THEN?
When asked this very question, Reddick chooses his words carefully: “He believes he’s on the side of the good guys.” This answer is, of course, fitting for a show that also features Benjamin Linus, Charles Widmore, the Others and “the freighter folk,” none of whom conform easily to good guy-bad guy characterizations.

EXACTLY HOW MUCH DOES HE KNOW ABOUT HIS CHARACTER?
While Reddick says he has been given key pieces of context on Abaddon’s backstory, which he declines to share, he says he prefers to “play to the mystery.” Well, it has certainly worked.

WHO DOES HE WORK FOR?
Wait, you mean he doesn’t work for Widmore? Maybe not. While Reddick declines to answer definitively, he says that we have been given information that could lead us to a conclusion. Further, he teases: “It’ll be crystal clear on [Wednesday] who he works for.” Like, maybe… Satan?

WHO WILL HE HAVE SCENES WITH?
Unlike Abaddon’s previous appearances, in which he had one-on-one encounters, this time he’ll get around more, it seems. “It’ll be with several of the main characters,” he reports. “He’s all throughout the episode.” The episode purports to show us what happened to Locke from the time he left the island via frozen donkey wheel until his death.

HOW DOES HE APPEAR AGAIN?
“Just as every single moment that Abaddon has shown up has been a surprise, how he shows up and how the character develops throughout the episode… just be prepared to be very surprised,” Reddick says.

We’re prepared! We’re prepared!

TVGuide.com: I have to tell you, a reader emailed me saying she was skeptical about your Lost future because of that Tyson chicken commercial you’re in.
Kelley: Oh yeah, my manager told me about that! A lot of people are bugging out about that commercial — “What are you doing?!”

TVGuide.com: But sure enough, Walt returns this week. In what capacity?
Kelley: Let’s see…. I don’t want to give anything away… but there’s a situation where he knows something is going on, but nobody told him. It’s that sort of thing.

TVGuide.com: What, does he get wind that Jack, Kate and the others are returning to the island?
Kelley: I’m just going to be talking to somebody, and…. Let’s just say I know a little bit about what’s going on, but nobody wants to tell me.

TVGuide.com: Now that the show is time-jumping around, do you get to play closer to your real age of 16? No more waving from windows or skewed camera angles?
Kelley: I do, and that’s a very cool thing. I don’t have to play this young boy anymore. I don’t have to change my voice or have them dub in someone else’s voice. There were a lot of things we had to do to try to make me sound younger.

TVGuide.com: When you first started the show, did you worry, “If I start to sprout, I’m going to lose my job”?
Kelley: I really didn’t expect me to grow that fast! It was just over a year period that I started sprouting up and my voice got deeper. I wasn’t really thinking about it. I didn’t know how long the show was going to go, but then they started saying “2010″….

TVGuide.com: Does Walt know that his father is dead?
Kelley: [Pauses] I… don’t think so. I’m not sure.

TVGuide.com: There’s talk that Walt actually was on the flight back to the island in spirit, because Hurley took some of his comic books with him.
Kelley: [Laughs] That’d be pretty cool. But I hope I get to go back to the island myself at some point.

TVGuide.com: But maybe since Walt has his telekinesis-like powers, somebody doesn’t want him back on the island. He could prove too useful to … someone.
Kelley: Right, that’s true. So maybe they’re doing a smart thing!
