Introducing Quentin at the tail end of Season 2 was great in solidifying the misdirection. They brought him on for one episode, sewed up Sean and then sent him packing. With that kind of maneuver, the character comes off as a 'one-off' and doesn't draw any attention to itself. So when he shows up this season, the viewer reaction is more "hey, that's the same character that "helped" out last season". I remember the first time watching it all play out, I was DETERMINED to beat the writers before they clued me in. But with all the twist and turns, I could NEVER get a leg up on them. Ack!!!!
