BL, big time

So, BL's father died. And she found out from an obituary that she discovered on the internet. Which she then printed out and stomped on.
And then OBVIOUSLY brought into the bookstore for sharing purposes.

There are a couple of things I don't really understand here and for which I'm not easily receiving answers:
1. Was she googling her father? How did she find this obituary?
2. Why the stomping on it?
3. Apparently we're going to receive even MORE money now that he has passed away. Will this happen soon enough for next month's rent?
4. She yells at her sister on the phone all the time. Why was she not informed?
And most importantly:
5. (well, this isn't a question...) This means BL is a real person. She was named as next of kin. Does that super freak anyone else out?
