The season 2 finale of S.W.A.T., titled "Kangaroo," was an explosive hour of television. A group of terrorists called the Emancipators is threatening to murder L.A. city officials in a televised execution ceremony that the squad must stop. In the end, they manage to foil the group's plans without any loss of life. It's a happy resolution to a scary situation, but the actual case is just one of the dramas going on in this episode.

In the midst of all the action, Cortez reveals some personal news to Hondo: She's been offered an undercover position with the FBI. Although Hondo doesn't want to see his captain go, he's supportive of her decision. By the end of the episode, Cortez announces that the FBI is offering her a five-week trial period in the position, which she plans on taking.

No official announcement was made about the fate of Captain Cortez, but when the third season premiered, she was nowhere to be seen. It was suggested that she stayed on after her trial period at the FBI and is gone from the LAPD for good. For viewers, the departure of one of the series' original leads felt abrupt, and with no announcement from CBS about Cortez's status on the show, there was confusion about whether the character was really gone – that is, until Sigman took to social media to set the record straight about her character's fate.
