You know, a lot of people are saying that it was Ben's intention to kill Locke once he entered the room. Based on the scene and the way it was constructed it was as if Ben had almost immediate access to cleaning supplies (gloves, towel, spray bottle w/ cleaner, etc.). Yeah he might have went in the janitor closet and such, or maybe he always carries around cleaning supplies in case he randomly decides to kill someone? It seemed planned to a certain extent.
Also, Sayid married the woman he loved. I assume this is the women we saw in one of his earlier flashbacks that he knew from his childhood, whom he refused to torture and eventually let her escape. And now she has been murdered? I wonder if that has anything to do with Ben or if it is just something that happened with no tie in to the main story.
Yep, same woman. I would not surprised if Ben had her killed and blamed it on Whitmore. You saw her funeral in the flashbacks last year, I think. Ben was at the funeral and Sayid confronted him.
