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 reading the background of the victim, a blue tape marker is visible under McGee's desk. (00:06:50)
Visible crew/equipment: As the team are just leaving the office for the crime scene, as Tony walks away from his desk, a yellow tape marker is visible on the floor. (00:03:40)
Continuity mistake: When we see young Gibbs sanding the birdhouse, the way he's holding the bird house changes between shots. It goes from being upright to on it's side. (00:35:30)
Continuity mistake: When Gibbs is talking to the chaplain about keeping daughters safe, the way he holds his coffee changes between shots. Note his grip on the cup. (00:23:00)

Continuity mistake: The way DiNozzo holds the little black book changes between shots when he is first examining it. (00:11:20)
Continuity mistake: When the victim falls to the ground in the pre-title sequence his eyes are closed and a pool of blood spills onto the floor from his mouth. When Tony and Ziva are examining the body and taking photo's of the victim, his eyes are now open and the pool of blood is gone from by his mouth. (00:00:50 - 00:03:10)
Other mistake: When EJ gets spooked near the end and turns to face a wall with a doorway to "North Stairway C", she faces the camera with her torch facing the camera directly. However behind her is a perfect shadow on The Wall of herself. This shouldn't be possible as the only source of light, as shown, is from her torch. Cade and Levin are in a different room so couldn't be their torches. (00:39:20)
Out of the Frying Pan - S8-E18
Continuity mistake: Vance slams the axe on the table and through a picture of the victim. However, when Vance removes the axe a minute later, the axe is through a different part of the picture. The 1st time the axe goes through the neck/shoulders of the man in the picture but when removed it's in the forehead. (00:29:50)
Out of the Frying Pan - S8-E18
Continuity mistake: The way the axe faces when Leon leans it against The Wall changes between shots. Sometimes it's facing left, others it's facing right. (00:28:00)
