In the show The Rookie , Talia Bishop doesn’t die or go missing; her exit is handled mostly off-screen and quite quietly.

In-universe: What happens to Talia?

In the story, Talia Bishop’s LAPD career stalls after it’s revealed she failed to disclose her foster brother’s criminal record on her application. This omission damages her prospects for advancement and puts her judgment and integrity under scrutiny.

Because of that, the character ultimately leaves the LAPD and transfers to the ATF (Bureau of Alcohol, Tobacco, Firearms and Explosives) as a Special Agent. That’s why, starting in Season 2, she is suddenly gone and later only referred to indirectly, with Harper stepping in as Nolan’s new training officer.

So, in simple terms:

  • She is written as having quit the LAPD.
  • She joins the ATF and continues her career there, off-screen.

Real world: Why the actress left

Talia Bishop is played by Afton Williamson, who did not return after Season 1. She publicly stated that she left the series due to experiences of racism, bullying, and sexual harassment/assault during production, including issues with a hair department member and a recurring guest star.

According to her statements, she felt the situation was not handled properly and chose not to come back for Season 2. Later commentary and fan discussions note that investigations did not clearly verify all of her claims, which has led to ongoing debate among viewers about what really happened behind the scenes.

Quick Scoop TL;DR

  • On the show : Talia’s promotion path is blocked after the truth about her foster brother comes out, she leaves LAPD, and transfers to the ATF as a Special Agent.
  • Off-screen : Afton Williamson left after Season 1, saying she faced racism, bullying, and sexual harassment on set; the situation remains controversial among fans because not everything was conclusively proven or publicly resolved.
