Sid (Fallout 3)

Sid is an insane human in Vault 87 He is trapped in Isolation Room 03.

Quests

 * Finding the Garden of Eden: Depending on the method one chooses to release Fawkes, Sid will attack the Lone Wanderer. If one frees Fawkes by activating the lab's emergency fire systems, this will open all the other isolation rooms, freeing both Sid and two centaurs. Although both are hostile towards the player character, they will also attack each other if either of them spots the other first. Sid most commonly dies in this scenario. Unlocking the door via terminal will result in Sid being hostile towards the player character as well. Picking the lock to the door does not turn Sid hostile, and he will keep acting as he was still locked in the cell. If the fire alarm is activated, Sid will attack even if his cell was already open. Sid will also become hostile if the door is "unlocked" through the terminal after the cell door is picked open.

Appearances
Sid appears only in Fallout 3.

Behind the scenes
In the G.E.C.K., there are dialogue options explaining that he killed all of the people in his isolation room and was moved to another isolation room by super mutants, which will explain the isolation room with two dead wastelanders and a raider.
