Continuity mistake: When Alicia is cleaning up Nick's vomit, she removes her gloves. When the angle changes, she starts removing them again. (00:24:45)
Character mistake: After Nick kills Calvin, and Travis arrives, Nick calls Travis "Nick" before correctly calling him Travis in his next line of dialogue.
The Good Man - S1-E6
Other mistake: At the end of the finale, Strand's yacht is way too close to shore. They wouldn't have had to use binoculars to see it if it was that close.
Audio problem: In the house as the walker is shot nearly point blank, the sound of the shotgun goes off before the flash.
Suggested correction: Travis is the one who says "Nick".
