Spoiler No. 1: Look for the castaways to venture inside the Black Rock — that ginormous pirate ship mysteriously landlocked on the island — to retrieve dynamite, in hopes of finally blowing open that damn hatch, where they plan to hide from the Others. Naturally, though, things don't go quite according to plan. "When you put dynamite that's 100 years old out in the middle of the jungle at unstable temperatures, it begins to sweat nitroglycerine," Lindelof says. "So the whole story is about how they get the dynamite from the Black Rock back to the hatch without blowing up. Not to mention that the monster is not really willing to let them do that." Which brings us to...

Spoiler No. 2: We'll finally get a look, albeit a partial one, at the monster. Is it, as Danielle Rousseau claimed, some kind of security system for the island? Lindelof's not saying, but he does hint that the unhinged French lady isn't the most reliable source on Freaky Island. "What her true motives are [will be] revealed [in] the finale," he says. "I would hang on to the concept of the loss of her own child and how far she would go in order to get her back." Hmmm, might she be in cahoots with the Others to snatch Claire's baby?

Spoiler No. 3: Hurley's seemingly jinxed lottery numbers, which appear on the hatch, will come back into play. "It would be very interesting to me if Hurley is one of the people to blow the hatch open," Lindelof teases. "What will happen when he realizes the numbers are on it? I don't think he'd be very excited if he knew, but they're very small. If you're standing on the wrong side of the hatch, you probably wouldn't see them." Hurley may not be in the know, but reformed junkie Charlie will stumble upon some valuable info of his own — that the plane that crushed Boone is full of heroin. That can't be good.

Spoiler No. 4: The raft riders — Michael, Walt, Jin and Sawyer (or should we call him James?) — encounter something shocking in the water. So what is it? "That's the $64,000 question," Lindelof says. "Telling you is sort of [giving away] the entire last scene of the show." But Lindelof will say that the quartet is not eaten by Jaws, "and there are no monsters in the water." At least not this season.

Spoiler No. 5: You will be talking about the cliff-hanger all summer. "It is beyond shocking," Abrams claims. "It's hair-raising. Also, something happens that is so terrifying, that's unexpected, and yet, it was right there, building for a while. It's one of my favorite turns I've ever seen." We'll be the judge of that.

TVGuide.com: As the live finale approached, did you think you had a chance to win?
Katie Gallagher: No, not at all. I went into tribal council [without expecting] to be attacked as much as I was. Why would they go there? We all knew Tom was going to win.

TVG: Are you mad at Gregg for tearing you apart during his tribal council speech?
Katie: No. I've totally forgiven him, and he really made up for it at the finale.

TVG: Was your final encounter with the jury hard to watch on TV?
Katie: Yeah, I was dreading that. I knew people were going to call me lazy. I just didn't expect them to attack me personally and call me "cruel" — because I'm not. I was destroyed when Gregg told me off. I was shaking and throwing up before [the live finale] even started. I wanted to disappear.

TVG: Why didn't you answer Janu's question? Don't you think that might have annoyed the other jurors?
Katie: I don't think so. I got a lot of "good answer" comments. Janu talked in circles, and Janu liked hearing herself talk. I went in there knowing I wasn't going to answer her question. We had our little [conflict] where I said she looked like a jack-in-the-box and she wouldn't accept my apology. She was so serious about it. I was like, "Come on, it's not like I attacked your soul." I said that her face, at that moment, looked like a jack-in-the-box. And it did!

TVG: So you aren't likely to be friends.
Katie: No. But we had a really good time [after the live show]. We do have one thing in common; we all shared this amazing experience together. So there is no animosity between the two of us.

TVG: Did you expect more votes than you got in the end?
Katie: I thought Coby would vote for me [just] to be different, so it could continue to be "The Coby Show." I am just glad that it wasn't a total sweep [in Tom's favor]. All I could hope for was at least one vote.

TVG: Would you have remained friends with Ian even if he hadn't stepped off that buoy?
Katie: Yeah, I had already forgiven him. I was just trying to keep my game face on. I didn't believe it [at first]. I thought, "It's just part of the game. I'll believe [the result of his sacrifice] when I see it." I was so wary of every move that everybody made at that point. I had accepted my fate in third [place].

TVG: When you stepped off the buoy early on, you didn't think Tom or Ian would take you into the final two?
Katie: I didn't know. I was pretty sure Ian was going to take me. Then again, they had a really strong bond and they kept saying, "Duke it out. Fight to the finish." I'm like, "I don't want to fight anymore. I have to go to the bathroom and I can no longer humiliate myself in challenges."

TVG: What's next for you?
Katie: I am turning 30 at the end of the month, and Jenn [Lyon] and I are going to Hawaii. That is all I have planned right now.

TVG: Would you do anything like this show again?
Katie: I would love to do The Surreal Life! Totally. Bring it on. I'll call everyone a jack-in-the-box. I've already put together the cast in my head. Tone Loc, Bret Michaels, Tonya Harding, Corey Haim. [Laughs] It would be great TV.
