However, it's important to clarify that this question can be interpreted in several ways, depending on what you mean by "survived."
* The main cast: All of the main characters - including Agent Gibbs, Agent Knight, Agent Parker, Agent Vance, and Agent Torres - were alive at the end of the episode.
* The episode's plot: The episode featured a complex plot involving a human trafficking ring. While several minor characters were in danger, ultimately, the NCIS team successfully rescued the victims and apprehended the criminals.
* The future of the show: The season 19 finale was a bit of a cliffhanger, as Agent Knight (played by Katrina Law) decided to leave the NCIS team to pursue her own path. It wasn't clear what her future held, but she was still alive.
