Man, everything is just going to shit. How the fuck are they supposed to get themselves out of this mess without the physicist?
I think he's going to stay dead in the Charles Widmore muses that the kid looks familiar but can't put his finger on it timeline, but Miles will save the day by being able to talk to the dead. Now, how they will keep Daniel's body from rotting so they can string out having Faraday around to talk to Miles for a long time is unknown. Hasn't it always been only the recently-dead that Miles can talk to? no history of, say, Medium-like talks with the sometimes-long-dead?
eta: Also, I think Big Boy is in the shadow of the foot, and that they don't detonate Big Boy. Dr. Chang believes the Lostaways and cements over the wall that's perilously close to being drilled through and releasing EM pulse. Maybe there's a tiny accident during that that causes a jump that gets Jim and Sun in the same time zone? It's gotta happen, right?
Where are they going with the Horus the good Dharma guy and his lookalike the black-jumpsuit wearing guy? Anything beside good/bad? Maybe Horus and the kinder, gentler Dharma guys jump ship, so to speak, and go live with the Others, who, led by Charles and Eloise, take them in. Then the black suited Dharma bums are the ones who get shot.
