Kind of makes me wonder in what order and for what reasons the non-obvious ones were crossed out.
Ben, Miles, and Claire would be the only ones that are not dead that are crossed out. Ben may be because, well, he's Ben. Claire is a mother. Miles is the only one there would be question about.
Dr. Linus:
Here's the best flash-sideways yet. No surprise that it follows Ben. I can't say enough what a fine actor Emerson is. He can play Ben Linus as kind, and caring man, and I can totally buy it. It's interesting to see just how different a man Ben is in this universe. He does have one thing that's the same as regular Ben: Alex. Though he's not her father here, they are still close. She's his "constant" so to speak.
Things aren't to rosy in the school. Principal Dickless isn't running things very well, and Locke suggests that Ben make a play for the job. A talk with Alex gives him the ammunition that he needs. However, when he tries to make his move, he's presented with the choice between the job, and Alex. In this world, he chooses her. It's such a sweet moment. The Ben of this world is unknowingly rectifying the mistakes of the other.
Jack and Hurley run into Richard, who is really scared and suicidal. Lately the writers have been all about showing us other sides of characters. Richard's usually calm exterior has been demolished. He takes them to the Black Rock to have them set the dynamite for him, since he says he cannot kill himself. Jack stays to talk, believing that since he's a candidate, he can't be killed by the dynamite, either. It's a gamble the pays off, as neither of them goes kablooey today.
The Ben in the main world has some more problems. The truth finally comes out that he was the one to kill Jacob. Illana is none too happy. She makes him start digging his own grave (the irony of which is not lost on him.) Smocke appears, and offers Ben a job as head of the island once he leaves, and tells Ben where there is a gun stashed. After escaping, and getting chased by Illana, Ben opens up his soul. It's a great scene where all the crap that's happened to Ben, and all the things that he's done come rushing back to him. He is truly repentant. He said he was only going to go with Locke because he's the only one that would have him. Illana comes to understand Ben, and allows him to return to camp. Did I mention Emerson is awesome? I don't know if I did. Well, Emerson is awesome, and Ben is a fantastic, complex character. Oh yeah, and Emerson is awesome.
Lost has to have cliffhangers, though. A periscope pops out of the water, and it's attached to a submarine, of course. Inside the submarine is OHSHITIT'SWHIDMORE! Well, things are about to get ugly.
