Episode #1.3 - S1-E3
Continuity mistake: When Leo's son throws his watch against the wall, it breaks into several pieces, which bounce off a surface just below the camera frame (it's an odd look, but could be a table or the floor, as we don't see where on the wall the watch impacted) - then they fly off to the right. But in the next shot, most of the watch's pieces are falling to the floor, directly down, and in a group (the prop man simply held out his hand and dropped them into frame). (00:37:40)
