Silver, 22, was a prostitute who worked for Colin Moriarty in Megaton before they had a falling out. She ran away with her share of her earnings (or so she says) and is hiding out in Springvale, just outside of Vault 101. Silver is now a pitiful psychojunkie and lives her life in constant fear of reprisal from Moriarty. Her name is a reference to her very light blond, almost silvery hair.
Following in His Footsteps, 300 Pieces of Silver: Moriarty will ask you to kill her in return for information about your dad. You have the choice to either really kill her, get a varying amount of caps from Silver to pay her debt, or tell Moriarty she is gone without taking any caps from her (which will earn you good Karma). Upon her death she will have 100 bottle caps if you offered to tell Moriarty she is gone with no reward or 400 bottle caps otherwise.
