Wait a sec...didn't you once write a fic which ended with Michael being the man in the coffin? I think I remember commenting on it (but don't worry, yours and mine aren't too similar, mine was from Walt's POV!)

Oh and do you mind if I ask, what were you thinking about with Eko? I was going to have the hatch implosion send him back in time to the day of Yemi's death, giving him the chance to save his brother...if we have the same twist at the end that would be too freaky!
