No, she wouldn't go THAT far, but still, if someone offered her money to do something, in this case, touch her little sister inappropriately, she'd do it.
THEN, like so many people, including me, are guilty of, she'd slowly start to realize what she did was wrong, probably when she sees Jeanette walking around with a paper bag on her head.
That's another thing to: Brittany says or does something first, then thinks about it later.
But, enough dragging this thread off topic.
