An Impossible Silence - S1-E11
Continuity mistake: When Catherine enters the precinct station, the desk sergeant places a small white file box on the counter. There's nothing else sitting next to this, but when the shot reverses, a tall black police radio with an antenna sticking up has appeared there. (00:16:10)
Character mistake: Ryan tells Jack that Darius turned into a werewolf right in front of his and Micki's eyes. Ryan and Micki never witnessed Darius' transformation into a werewolf at all.
