Are the events we see in Sawyer & co's time-skipping flashes the past of the main timeline or the Sideline or neither? Would the Charles Widmore who employs Desmond, and his wife who is the terror of the domestic service industry remember the guy who looked like their son coming into their camp on the island? Regarding this episode, does Dr Chang, or whatever name he uses in LA remember the guy who looked like Hurley who came to the island in the 70s and rode in a van with him and with a guy who looks like his son, the cop? If Charles Widmore visited the school where Ben & Locke teach would he recognize either of them from the encounter in the past, or when young Ben was brought to his camp to be healed in the Temple?

Did Widmore or Sawyer in their sitdown in "Recon" reference their earlier encounter in the jungle when Sawyer was timeskipping and Widmore was little more than a kid who is overly confident in his woodcraft?
