Madison Li

Doctor  is a scientist working on portable fusion power and hydroponics experiments in Rivet City in 2277.

Background
Born in 2229, she used to be part of the group of scientists that worked with James on Project Purity before the birth of the Lone Wanderer. Despite James' renewed efforts she remains skeptical of the project. Dr. Li is the first distinct face that the Player sees, during the birthing scene, as she carries the newborn Lone Wanderer away while Catherine is going into cardiac arrest.

After escaping from Vault 101, James returned to Rivet City and tried to recruit Dr. Li in his efforts to revive Project Purity. She refused. According to the Fallout 3 Official Game Guide, she had romantic feelings for the player's father, but hid her feelings to respect his marriage with another scientist, Catherine. When James left, she felt betrayed.

During the events of Broken Steel, the Lone Wanderer is told that she proceeded to leave the Capital Wasteland and travel to the Commonwealth to pursue other scientific purposes, allegedly because she could not stand the Brotherhood Scribes' involvement in Project Purity. After this point she is never seen again.
