I wasn't shocked so much as resigned -- because in the hiatus between Season 3 and Season 4, they were showing The Omega Factor, which Chris Boucher was also involved in (I can't remember in what capacity). It was also a fairly bleak-ish show, Our Hero was certain that there was some kind of conspiracy going on, and every episode he would always miss out on getting the evidence. So when "Blake" aired, my reaction was "Typical Chris Boucher!" (grumble grumble).
