You help Sarah Weintraub overcome her agoraphobia and she agrees to travel with you but before she can leave with you, you, have to go out and find someone to tend to the Vault 21 hotel. Maybe her associated perk could have something to do with luck or Gambling seeing how thatís what her Vault was geared around. I liked her as well, but I don't think there really is a base for making her a companion. Itís too much of a flat character, I think. Also she really isn't a fighter. Someone like Sunny Smiles I'd love to have as a companion.
