Rebecca has the reputation of being able to acquire things. If you need something, whether blood from the blood bank, illegal drugs and weaponry, cash, even a release from jail before the sun comes up, she's your woman. She seems to consider it her duty to aid other Kindred in various ways, and although she does tend to ask for favors in return, it's never something that would require any great difficulty.
Her natural talents seem to rely on understanding the skills of her associates and how best to apply them to a task. However, although she naturally gravitates towards a sort of command structure, she's more than capable of working simply as acquaintances and through associations.
