I got Special Agent Caitlin Todd! Which "NCIS" Agent Are You? You got: Special Agent Caitlin Todd You’re smart, determined, and sassy, and you pretty much always get what you want. The few people who dislike you still respect you, but let’s be honest: Most people like you. You’ve got moxie!
Special Agent Ziva David was originally assigned to the "NCIS" team as a Mossad liaison after the death of Special Agent Caitlin Todd at the hands of rogue Mossad member Ari Haswari, who also happened to be her half brother. Despite being fluent in many languages, including English, Ziva often endearingly misinterprets slang phrases used by her team members.
Caitlin Todd was a agent on Air-Force One, the plane that carried George W. Bush and on which he had all his press conferences while he was on his way to other important appointments, but was mysteriously poisoned through the clothing. Kate learned about Gibbs' brash techniques the hard way, was fired from Air-Force One and hired by Gibbs and NCIS. Kate is the big sister of the group and gets along really well with Abby and Tim McGee.
