seriously. who is in the coffin? and why was Jack so touched/affected?....while kate was bewildered on why jack would even think that she would go to the funeral? Is it walt? michael? <----maybe he turns on them, maybe he's working for Ben, so Kate feels no need to go. is it juliette? ben? post away!!!

I have so many speculations that it makes me dizzy, but according to the Doc Jensen interview with our favorite LOST producers we have reasons to smile!!
From the interview:
"We could be winky about the coffin all the way through season 5. But that was one of the first things we talked about when we got back to work on the new episodes: We definitely have to show who was in the coffin. That's the primary superstructure of the season." - Damon Lindelof.
(Crossing my fingers that it's not a tease.)

My original theory was either Locke or Ben, but now I'm leaning toward Sayid. Especially after his episode when we find out he's working for Ben..

I think whoever it is is also the sixth member of the Oceanic Six. But I really have no idea....

i dunno, i feel like its somebody were not too permanetly attached to. Miles Straume maybe? just a guess, im just glad that we'll definetly be getting this answer.
