You all missed the one point that was clearly shown in this, Sarah and Dave are brother and sister. When family meet, united in Spirit with Yahweh as Father, they act like family. There is no barriers between brothers and sisters. If I have something you need, even though you just met me and you are my brother, I do all I can to help you. What Sarah did is nothing out of the ordinary, her brother needed help and she gave it.
