Loose Lips: A Dog's Story

This is the only episode of the series in which Jake Epstein (Cam Dunleavey) does not appear.

Spence (Michael Seater) wears his wristwatch on his left arm. In a short scene where he and Zack (Robert Clark} are discussing their dog-tracking strategy (about 5:17 into the show), suddenly his watch is on his right wrist in one shot.
