Sid (Fallout 3)

Sid is an insane human in Vault 87 in 2277. He is trapped in Isolation Room 03.

Background
Sid is one of many unlucky super mutant captives. He was captured to be dipped in the "green stuff", in order to help the super mutants in creating an army similar to the Mariposa army on the west coast.

Quests

 * Finding the Garden of Eden: Depending on the way you choose to release Fawkes, Sid will attack you. If you free 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 you, they will also attack each other if they spot each other before spotting you, during which Sid most commonly dies. Unlocking the door via terminal will result in Sid being hostile towards player as well.

Notable quotes

 * "No! It's all over me! I can feel it... it's invading my mind"
 * ''"Get out of my head! Get the fuck out!
 * "Aaaaagh!"
 * "Can't you see?! They're all dead! It's all my fault!"

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 2 dead wastelanders and a raider. While sneaking, super mutants will be talking about throwing only the strongest people into the "green goo" to make more super mutants who will destroy humans which is why Sid is locked in the isolation room - possibly with the early symptoms of transforming.
