I think this was on the last episode, but do you remember when Eloise was talking to Penny in the hospital? She said something that really got me thinking. She said, “This is the first time in a long time that I don’t know what is going to happen next.” Makes me think that this whole time we’ve been seeing her as her old self that she is somehow from the future.

Can’t wait for the next episode!

I mean, perhaps Ben wanted to be THAT guy, but really wasn’t? I dunno…maybe that’s too much of a stretch.

I think the big thing right now is that suddenly no one has really seen him…and like Josh said above, maybe Jacob is someone we already know.

I’m not into the romantic quadrangle, but I agree – I couldn’t help but feel terrible for Saywer and Juliet when Kate came down that ladder. Talk about an awkward moment!!! No surprise, that Kate ran away again…

I love what Sayid said to Jack when he came up out of the water. “If this works, it might just save us all. If it doesn’t, at least it will put us out of our misery.”

Since Miles gets off the Island, I think Sawyer, Kate, and Juliet ARE going back to 70′s USA.

Also, who are the characters that are planning to detonate the bomb?

Widmore (accounted for in future)
Eloise (accounted for in future)
Sayid (not accounted for in future)
Jack (not accounted for in future)

What if Jacob is Jack? The earliest mention of Jacob is AFTER all of these 70′s events. He wasn’t mentioned at all by the hostiles. They didn’t bring young Ben to “Jacob” but instead they just reference “the temple”. Perhaps the bomb blast, or whatever energy is released makes Jack some kind of disembodied power? 30 years would make Jack an old man (like the flash of Jacob in the cabin), and it would make sense if Christian was acting as his surrogate, and he brought his sister to the cabin too. Also, they’re always referring to Jack AND Jacob as “great men”. Even Jack’s tattoo means “He walks amongst us, but he is not one of us”. Ben’s never seen him either. If “the island” told Locke where and when to meet with his former self, perhaps that is Jack going back and forth, making sure certain events happen in order to produce a particular future?

It also could be that there’s some kind of war, like Island/smoke monster VS Jacob. The smoke monster wanted Ben to help Locke. Locke is getting instructions from the Island too. And he’s planning on killing Jacob? Or is Jacob actually telling Locke this because it causes some kind of event?

I don’t really see any holes as to how Jack “for sure” couldn’t be Jacob.
