When Ziva and Gibbs walking through the parking garage ,they are playing through a assassination scenario for Ziva's father Dinozzo was the first to get "shot" and Malachi was the second and as Ziva and Gibbs approach the third target if you look in the far background you can see Dinozzo next to a car head banging and acting a fool.
When Officer Hadar stops Gibbs on the street and asks him to meet with Eli David, it is daylight. They get in the car, and there's a commercial break. After the break, Gibbs and David are sitting at a window, and it is fully dark out.
It's supposed to be a surprise that the person NCIS is looking for is Malachi from Mossad, but they gave it away when we see Malachi's side profile as he walk's past Ziva on the sidewalk while Ziva is scanning credit cards.
