What happened at the end of Kin?

Quite an interesting book, but I’m really a little confused by the ending. What actually happened? And what happened to Bernice? When Anne explained what happened with her mother coming to see her at the bar what was that? Personally did not find too much in the book to question. It’s a great book to discuss for
the time like, of course, women wearing hose or drinking in the afternoon, but the ending was a little confusing, and I would love the opportunity to talk with somebody who’s listened to it or read it.
