Sydney

 is a relic hunter in the year 2277.

Background
As a child, Sydney was orphaned when her father was killed during a weapons trade off at the Statesman Hotel. She had to wander D.C. alone, but she was able to handle herself because her father had taught her how to handle and maintain guns, and to upgrade them since she was young. Sydney then became a relic hunter and did some work for Abraham Washington. In her own words: "After he loaded me up with caps, I got piss drunk, got laid, and was happy for the first time in a while. I haven't looked back since."

Bugs

 * There is an exploit where it is possible to receive an unlimited supply of Sydney's 10mm "Ultra" SMG in perfect condition and 10mm ammo. It can be found under the Sydney's 10mm "Ultra" SMG article.
 * You can't pickpocket Sydney after recruiting her - neither during the quest nor after completing it. You just get the talk option when crouching.
 * When she walks into the Museum of History she sometimes gets stuck on the stand where the dinosaur skeleton is or on a bench in the same room.
 * Sydney can get stuck on her way from Rivet City to Underworld. Usually by a train in the metro tunnel she travels to get to the Mall. She can be unstuck by pushing into her and talking to her and backing away to reset her walk path. It's a little tricky and may take a few tries but eventually will work.
 * When she's in the bar in Underworld, she can sometimes die and will be slumped over the floor. It is unknown what causes this.
