Character mistake: In the scene, where Jeanne tells Tony that he never said he loves her, besides after sexual activities. This is not true. In episode 15 "Friends and lovers" Tony ends a phone call saying "I love you."
Other mistake: When Ziva signs the will, she signs it with her real name - "Cote" is visible.
Suggested correction: No. We see in the closeup Ziva David writing her name, and the shot cuts away just as she starts to write the last "d" in David (timecode 00:28:00).
