When Ziva and DiNozzo burst into the cabin to look for Amanda, a large cobweb gets caught on Ziva's gun, but it immediately disappears in the next shot.
At 10:19- An NCIS agent should be able to tell the difference between an opened door and one that is closed.
While Abby is waiting in the interrogation room, being questioned by McGee, she keeps saying she's refusing to speak. She pretends to zip her lips closed and only opens them to say a few words. Throughout the scene, she keeps inadvertently closing and opening her "zipper" in opposite/inconsistent directions to speak or not speak.
Three time people bang their noses because Abby locked the door to her lab for the first time. However, the door swings toward the person opening it. No banged noses should occur under these circumstances.
When Ziva catches Tony in the elevator a piece of yellow masking tape is seen on the floor outside the elevator.
When McGee, DiNozzo and Palmer all banged their noses into Abby's door, they all complained that she never used to keep her door locked. The door was hinged to swing outwards so they would've banged into it no matter if it had been locked or unlocked. The complaints would have been appropriate if it hinged to swing inwards.
SecNav speaks proudly about his cigar being Cuban, but then allows Dirctor Vance to offer him a light from a 'Zippo' style lighter. A true cigar smoker would never allow such a thing as the flame from a liquid fuel lighter taints the flavour of the entire cigar, a good Cuban would only ever be lit by a gas lighter, usually one with a compressed jet flame.
