Pierre's Arm - Barracks Video?
Everyone's always pointed out that in the Barracks video, Pierre doesn't use his left arm, surmising that the incident took place before that time, but when we see the barracks video its when Ben and his father arrive on the island. Obviously that's pre-incident, where we see his arm get crushed. Some of the newer looking videos also seem to have him having use of his arm.
Also, on a completely unrelated note, my boyfriend just pointed out the scene where Locke meets Horace (which some speculate may be Esau). Horace gets a nosebleed, much like the losties skipping around. Anyone have any speculations on that or links to threads? I'm searching but not coming up with much.
