how did seth lose his leg in the rookie

In The Rookie , Seth loses his leg after being shot in the line of duty while saving Officer John Nolan during a shootout.

What happens to Seth?

• In Season 7, Episode 16 (“The Return”), Seth steps out from cover to protect Nolan during a high‑risk call. He is hit in the leg at close range by a shotgun blast.

• The damage to his lower leg is so severe that doctors perform a below‑the‑knee amputation to save his life, effectively ending his active career as a police officer, though he qualifies for disability.

In‑story explanation

• The scene is framed as a moment of redemption for Seth: despite his history of lies and bad decisions, he acts on instinct to protect Nolan rather than himself.

• His injury becomes a major turning point for the character, leaving him emotionally “pretty damaged” and unsure who he is or what his future holds after losing both his job and his leg.
