Continuity mistake: During their first day's investigation of the double homicide Tony is wearing a grey suit, white shirt, and burgundy tie. On the second day, while Tony is wearing a dark suit, light blue shirt and dark blue tie, when Gibbs tells Tony to go see what Ducky wants in Autopsy, Tony is back to wearing what he wore on their first day. Then at Tobett's house, Tony is again wearing the light blue shirt and dark blue tie. (00:04:30 - 00:31:00)

Visible crew/equipment: When Gibbs and Ziva enter Second Chances to question the owner about Curtis, in the overhead shot Gibbs stops beside the counter, and the red tape mark is visible on the floor between his feet. (00:18:20)
