I was glad to see "evil Ben" back last night, as opposed to "turning into a pussy Ben".
Also, I thought last night's ep gave us yet another hint that Jacob is time-traveling Locke. When Locke got all nervous about going anywhere near the beam of light but didn't want to admit why, I think it was a hint that he realizes the one thing that absolutely cannot happen is for two versions of the same person to encounter each other, at least knowingly.
When Locked tried to see Jacob's face a few seasons ago and things went kablooey I think it was because he couldn't look at "himself."
