Anyways I think there's evidence that Beatrice is some sort of seeress. The poem she gives the LW for his birthday seems to predict his fate like how he dies trying to activate the water purifier in the end of the main quest, and a memo posted in the diner says that she offers tarrot card readings to the residents.
I wish this was explored more in the game because the only time we really see Beatrice alive is during the LW's 10th birthday. I'd like to know just what her relationship with James was, obviously she saw the LW as a child figure that she helped raise but maybe she had some sort of romantic interest in James too? Also it's cool that she's actually somewhat of a psychic, it's one of the few supernatural things to exist in Fallout 3 like the Dunwich Building.
