A young woman with dark-green hair, Lorraine is one of a half dozen scavengers working for Sammael. She views the Regulators as a strict but acceptable police force, and is unaware of their true intentions. She also sees the Blades as the violent group that the Regulators portray them as.
Lorraine can be spoken to for a little basic information on Smitty, Miles, Caleb, Jon Zimmerman, and Tine Taylor. Other than that, she has little to say. Lorraine will not take part in the battle between the Blades and the Regulators unless attacked by either.
The following is based on Fallout cut content and has not been confirmed by canon sources.
Much of Lorraine's dialogue is actually closed off. She was to be one of the major players in the Romero-Julianna love quest, informing the Vault Dweller of the Rippers' hideout's traps, and of the duo's attractions. Her dialogue was not recent by the time Romero and Julianna were cut; Romero was slated to be a Blade, not a Ripper, this was fixed in a later dialogue file as can be seen above.
In addition, she would have talked about Adytum and L.A. before the Great War, mentioning that the people in the pre-War world did all sorts of important things, like making computer games. Should the player character respond that doing such is not important would make Lorraine snarkily point out that "without computer games, you wouldn't be playing this." [Fallout]
