I'm surprised that noone has brought this up but remember in episode 6 when Kate appears in Jack's bed and said something happened to Aaron but to not talk about it and Jack talks to Ben on the phone and he looks beat up and says something like he had to take care of some business? Well I think that Ben is somehow responsible for whatever happened with Aaron (as well as whatever convinced Hurley to get on Flight 316 and however Sayid got arrested)but even more interesting it looks like Ben is on a dock. Who's been living on a boat? Desmond and Penny. What better opportunity would Ben have to kill Penny like he promised Widmore he would then his one trip off the island? There's many implications that could stem from this (Desmond finding out and seeking the help of Widmore to return to the island to kill Ben?). Anyway what do you think about this?
