Sheriff

The Sheriff is an NPC and boss in the Desolation.

Gregg
The Sheriff does not trust Gregg and tries to kill him after Gregg kills the Showerhead.

Fate
The Sheriff's fate is decided by the player after her boss fight. If she is killed, she disappears from the game. If she is spared, she will stand in the Tower of the Shower and not speak.

The Sheriff appears again in TAFB 2, whether she was killed or not. However, she is erased shortly after her appearance.
