It is hard to reconcile the will, with the actions. If haileys Mother liked her sister Clare so much, why did she not provide something for Birdie if Hailey chose not to live in the house? I suspect everyone. I am not sure about Birdies motives, she has had a long time to learn how to act correctly around the "Family". How much of Haileys "Fears" while growing up were caused by a displaced family member. I think the Birdie back story is going to be interesting to follow. They are all out to get poor Hailey.
