Yeah, Locke was Deadwood guy ever since crash #2. Sucks. For four seasons, we've seen Locke struggle with his purpose, not being wanted, his dad, etc. Just when it seems he had found his way, they slap us in the face with it. He's dead. For reals.
Will be very interesting to see if we get *original* Locke back, when the timeline reboots.
P.S. I made this discussion "sticky", so it'd stick at the top of the group for a bit.
