Just chipping in with my take on if she asks you to help out and really to me it depends on what help she asks for, you'll have to judge whether it seems reasonable and what it costs you, basically if the answer are yes and nothing then saying no is being a jerk, if the answers are no and a lot then its definitely pursuing to still help.
more importantly though, I wouldn't worry about it. Don't give it any thought until/unless it comes up, no need to borrow trouble from tomorrow, today has plenty.
