Yes I guess many people online remember when ABC asked Darlton to do one Sawyer's centric at the beginning of the season 2 but they changed for the story and did one with mike anyway, they filmed a little (i dunno if they filmed the entire episode) but look those unseen promo pic for this episode we'll never see :( and also some pics of the set. I think sawyer's fan deserves to see it after the lack of our conman the last season, I wish the next season we'll see more of him...
