Lehu a Lehu - S6-E2
Visible crew/equipment: Danny is supposed to be looking for the suspect in the woods by himself and you can see another person on the top right hand side of the frame. The crew member looks as if he knows he is in the way and slowly backs away. (00:35:15)
Character mistake: Neil is looking over the model of the USS Enterprise close-up in Steve's office. The island structure on the flight deck is backwards.
Continuity mistake: When Jerry is on the video call with Kono, he is wearing white makeup with red around his eyes, but when the shot shows him and the phlebotomist in the room, the makeup is gone.
Factual error: In episode 17, Danny's Camaro is subjected to a number of bursts from a mini-gun, riddling it from stem to stern. In episode 18, Danny's daughter mentions that he had just had it repaired. There is no way an insurance company would not total that vehicle, since it would require replacing or using "Bondo" on virtually every body panel, not to mention mechanical repairs.
Continuity mistake: The Russian spy Anna Novick picks up Dalton in a Silver sedan and continues into a shootout. The Sedan's identifying badge (Hyundai) switches between being present and not, throughout the entire scene. (00:23:50 - 00:27:25)
Ua 'o'oloku ke anu I na mauna - S6-E3
Other mistake: The victim has been dead for six weeks, but when Steve and Lou enter his home, the printer is still printing bills. (00:19:35)
Chosen answer: They are Junior's SEAL buddies.
