Hey, I'll bet that the Sawyer-nicknamed "Other Others" that pursued and shot at the time-travelers in the outrigger in Season Five are going to turn out to be people from Widmore's group. They seem to be the only group with guns who know there were people on the beach, so they headed out that way once they set up camp to "take care of them" in a manner similar to Keamy. Instead of seeing the current beach group, however (Jack, Ilana, Ben, etc.) they saw the time-travelers (Sawyer, Juliet, Daniel, etc.) and proceeded to shoot at them. What do y'all think?
