at the beginning of the episode with the flashback a new actor played the young version of Shawn Spencer.... the previous actor being Liam James... the one featured this week being Skyler Gisondo, who some may recognize from the House episode where the little kid though he was abducted and had alien tech in his body and whatnot...that is all...

Haven't watched this weeks episode yet, but I was wondering what they were going to do with the flashbacks at the beginning, because the young Shawn actor was starting to get kind of old.
