I don't know if you guys noticed but there was an ad last night during one of the commercial breaks for Octagon Global Recruiting which said they were looking for people for the dates of July 24-27 which is the same time as ComicCon it has something to do with the DHARMA Initiative from what I hear this may be similar to the Find 815 thing they did before. I guess we'll have to wait for ComicCon to see.
Also if you watched the end of the episode they said they had actually shot 2 different endings which were aired on Good Morning America this morning here is a video of it I found on You Tube

It would be interesting to see what would have happened if it was actually one of those endings. But from what I heard the reason they had 3 was in case somebody found out and tried to spoil it for people they could have had other endings prepared.
