It really matters to me that it's Locke, and not some island defense system posing as one of my favorite characters. I care about what happens to John Locke the character, and how he turns the tables on Ben. Either way Ben is screwed, but I'd prefer the island corners him into following the character I've been following for five seasons, rather than some island doppleganger. It makes sense that Illyana is working for Widmore. As the lines are tightening in these final seasons, to introduce a third "faction" might send people into mass confusion. Does anyone else wonder if Cesar might not be dead? I hope he is, just because that was a great, shocking moment, and it would be lame to dial it back... but they seemed to go out of their way not to show the body after the shot. I'm probably reading too much into this.
