Maya is an FBI agent doing surveillance on the hotel room in Under Covers (episode).
Maya is Yussif's partner. The two are tasked with doing surveillance on married assassins, Jean-Paul Ranier and his wife, only to later discover that the two real assassins are actually NCIS Special Agent Anthony DiNozzo and his partner, Mossad Liaison Officer Ziva David.
Upon the FBI and NCIS joining forces, Maya goes undercover as a maid to plant a bug. She and Tony flirt with one another but the moment is interrupted by Ziva who tells Tony that she's pregnant.
