Sid (Fallout 3)

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

Inventory
Sid has an abnormally high amount of health for a human civilian (almost as much as a Super Mutant Brute). This might be due to some form of unique mutation caused by an FEV experimentation on him (or he may simply be a "boss" enemy, like Commander Jabsco, the Vault 106 Survivor, Mad Johnny Wes, or Vance). Sid also wears a Merc Grunt Outfit.
 * If the door is unlocked with a Bobby Pin, Sid is friendly but uncommunicative, screaming:
 * "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!"
 * If the door is unlocked by hacking the Medical Wing Maintenance Terminal, Sid will be friendly as above; until you unlock the Room 01 Door, then Sid will attack you.
 * If the door is unlocked by hacking the Hard terminal outside his door, Sid will then attack you. (Confirmed on 360, PS3, PC)
 * When the door bolts are blown, Sid turns hostile; even if the door was previously open.
 * 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.
 * If Sid exits the room by glitching through the door (by walking against it until he is forced through) he will also be uncommunicative(see above).
 * Sid may just be in the process of mutating into a Super Mutant, explaining his aggression, insanity and high health compared to other NPC's.
 * In the construction set, there are dialogue options explaining that he killed all of the people in his isolation room and that he might have been captured by super mutants
 * Upon returning to Vault 87, if you have not released Sid he will be dead in his cell.
