Lost

In Lost's third season, we met a young Ben played by Sterling Beaumon via a flashback.  Now when Lost returns in two weeks with "Namaste" in two weeks, Beaumon will reprise his role.

According to what Beaumon told E! Online, his upcoming story is "very major, and it's going to change Ben forever."  According to the young actor, this very major thing "involves himself and yes, it is a trauma…Before the change Ben's a nice, good kid…and then one second will change his life forever."

Sterling goes on to describe the rest of his four episode arc by saying "Ben will [come to] know everything about every little bit about the Island. We're not going to learn more about the past with Dharma, we're going to learn more about the past of the Island."
