The “Lost” 100th episode airs tonight, April 29, on ABC – so Lost fans are rightfully excited. Any time a series reaches the 100th episode milestone is a big deal, but with Lost, fans are hoping the 100th episode, “The Variable,” brings some extra island answers.

The Lost 100th episode synopsis on TVGuide.com doesn’t give us much to chew on, however: “Faraday discloses what he knows about the island, beginning a time of reckoning.”

Awhile back, the cast and crew celebrated the Lost 100th episode with a very special Ace of Cakes cake to celebrate the big 100. The Ace of Cakes Lost 100th episode show called “Lost in Hawaii,” will air on May 9th on Food Network.

Take a look at the cake that Duff and his Charm City Cakes crew created for the Lost folks. (More pictures of the Lost 100th episode cake)

Lost will conclude its run with a series finale in May 2010, it’s sixth season.

Executive producer/co-creator Damon Lindelof commented on Lost running its end, saying, “We’re fairly certain that, had we not been given an end date, the show might have been canceled by now, because we would’ve had to continue spinning our wheels and stalling. It’s a finite idea. Once Carlton and I had gotten through the first 30 or 40 hours of it, it became very clear to us that we were ready to take the show out of question/mystery mode and into resolution mode. And we couldn’t do that until we knew when the show was going to end.”
