This story contains speculation for the final season of ABC's "Lost."

It's the final season and the fate of the entire cast of "Lost" is up in the air.

But, according to actor Michael Emerson, Benjamin Linus may be one of the ones to go. During an interview with E! Online, Emerson revealed that one of the upcoming sideways flashes will center on his character (who is now a teacher) and it will be one of the more important episodes of the seasonal arc.

"You'll see the biggest Ben episode ever in the next two weeks," he said. "It's a big one, and it may be the last one of the Ben episodes... It's worth watching."

As previously revealed, Ben will have a connection to John Locke (Terry O'Quinn) and that will be explored through the flashes for both characters. Their journey in the newly re-created world will parallel what has gone on during their time on the island and it will be a cornerstone for the series.

"They have an important relationship," he said. "Yeah... friends. Think of it this way - he has all the same characteristics that Ben has, but they're in different quantities. He has some of the same urges or fantasies, but they're not as powerful with him."

"Lost" airs Tuesdays at 9 p.m. ET on ABC.
