After watching how “Lost” ended, there was one scene in particular that I kept coming back to as proof that for at least three years, Damon and Carlton knew how they were going to end it all. That scene wasn’t even in an episode during an actual season, but was in fact, a mobisode from a series entitle “Missing Pieces” made in between seasons 3 and 4. So for anyone who hasn’t seen it, (or anyone who wants to see it again) here it is. And know this, that man IS Christian Shepherd. The Man In Black lied.
Here’s a fun alternate ending from the Jimmy Kimmel Show. His other ones weren’t too bad either, but this one sort of fits in with the above video.
