NCIS-verse: Walter O'Brien's Daughter

Riley O'Brien is Walter's Daughter. Her mother Lindsey O'Brien died when she was 10, she was then recruited to the CIA and work there for 10 years, her fifth year she found out that her mom was murdered. She left the CIA 5 years later for Homeland but than moved to NCIS because the Homeland only wanted her because of her dad. She goes back to LA for holidays and when she was off. Her best friend is Ellie Bishop and she is dating Angus "Mac" Macgyver. She met Steve McGarrett while working on an op and Ellie Bishop while undercover for the CIA. She has been secretly investigating her mom's murder. She currently works for NCIS in the MCRT under Gibbs. She is 25 years old. All right to characters to except OC got CBS. I am including Magnum PI because I think and want them to do a Hawaii 5 0 Magnum PI crossover.
