Dan in Santa Monica: Please, oh please! How about some good scoop on the Lost finale? Who dies?!
Okay, guys, here’s the thing. What happens in the season finale is so big that I honestly would not only be banned from all ABC sets from here to eternity, but I’m not sure how I could ever look Damon Lindelof in the face again. And you know I love my D.L.! But I will reveal a smidge of info to tide you over (and hopefully prevent you from throwing rotten tomatoes at me) in the spoiler section below.

Kristin from Kristin's Office: What are the two things you can tell us about the Lost finale on May 23?
Excellent question, Kristin! Here they are:
1. The game-changer involves Jack and someone else.
2. A fan favorite will sacrifice himself for the good of the rest of the Losties.

Dana in Philadelphia: Please tell me that we get to see some Jack and Juliet nooky before the end of the season! P.S. If Juliet dies, I'm no longer watching the show. P.P.S. That was probably a lie.
HA! Right there with ya! I'm already giddy with anticipation for season-three DVDs of Lost, much less season four. Anyway, I don't know about no nooky, but I do believe Dr. Juliet Burke is sticking around for the foreseeable future. Yay!...Please don't throw garbage at me. I like her.

How pissed am I about the game-changer being about Jack? >.<
"and another person"... maybe you're right and it's about the Jack/Locke confrontation. But would the news have leaked if its consequences are so huge, if their fight is the super top secret "snake in the mailbox"?

And the person who dies doesn't look like Charlie. He already risk his life for the group in episode 21 with the underwater cable.

Maybe Charlie decides to sacrifise himself in episode 21 but dies in the finale.

I don't know. Fan favourites are: Hurley, Sawyer, Charlie, Sayid...

The game changer involving Jack - it sounds like he kills someone.
Some posters on the Fuselage think it could be Kate, in friendly fire, like the rumours suggest.

That would be a way to shock people! Everyone thinks that Charlie is safe after his bet against death in his episode, and then in the finale...! Good theory.

What if Jack kills Sayid? *cries* I don't know how people will react to Kate dying because of Jack.. it's huge.
Either way, he will be dead to me.

When I first read the spoiler about a fan favourite sacrificing himself I immediately thought of Sawyer.
But if killing Cooper has chaged him for ''worse'', made him darker and colder, then it wouldn't really fit. But also it could.

I thought about Sawyer too. There's that spoiler about Hurley playing a big part in the finale though, and he's a fan favourite...

I think Jack kills Locke in the finale.

I just can't see them killing off Locke. He's the only character which seems to be connected to the island.
But I expect the death to be shocking so it's possible.

It definitely sounds like Jack kills someone, but what if he just ends up becoming the Others leader?
How disappointing.

Locke would make sense story wise, but the fans would rebel all over the world... Locke is a very loved character, Damon said he's the core of the show... I don't know. Jack could kill Ben, but it won't be shocking. It may change the game though, especially if Jack becoming the leader of the Others manages to stop the battle. What if the Others aren't working for a bad purpose, but a good one. But, as Richard said, Ben is keeping them away from the big things. So no more Ben, and Jack reunited the two groups, or at least make the "war" stop. The game changes because there is no more Losties vs. Others.
I know, it's the lamest theory ever, lol.

If not Locke, then Sayid. Either one, my Jack hate would increase to unbelievable proportions.

Question: Hey, this is cool! I've never been to one of these before...but anyways, do you know if the Sawyer/Kate thing is going to last on Lost? I'm a Jater myself...

LOST: Spoiler: Supposedly, it will last for a "while". How long? Unknown yet.

But making Jack kill someone wouldn't be a too much bold move from TPTB? I mean, considering their hero worship. Even if he killed a random Losties like Bernard, it would be a "good" guy. Unless it happens by accident, like that rumor saying Kate gets killed by friendly fire caused by Jacksus. In that case, he isn't really responsible because the person stepped on the line of fire miscalculating the situation.

But if Jack kills someone, my bet is Sayid.

I still think the one sacrificing himself could be Hurley, he's a fan favourite... on one hates him, the worst feedback I've seen him getting is indifference. If Charlie dies in episode 21, is because he finally decides to "look death in the face, and say Whatever". His death would affect Hurley immensely, seeing as they're BFF, and could lead Hurley to make something equally heroic in the finale. The points against this theory are that the producers once said Libby's story isn't finished, and that with Hurley would be gone the focus on the numbers' mystery.

I agree that she hasn't a lot of spooiler stuff regarding ships. I remember people asking her about the Skate in store for the return of Kate at camp, and she just said something very vague. And she said there would be something between Jack and Juliet, but so far everyone is talking about them as "war buddies" in the upcoming episodes, nothing romantic yet. It's also hard to say what her phrase means: does it hint to the "temporariness" of Skate, or she's just saying all she knows is about the near future, and they're still together there, but her info are limited just to a certain amount of time?

Jason and Pryce are Others. Still no idea who Greta and Bonnie could be.
