Hermione ached, if losing Draco was hard - this was impossible. It was the right thing to do, the only option that made sense to her. She was in danger and so were they. If they moved to Australia, if she survived this war, this might ensure she had parents to come home to at the end of it. Losing them to the death eaters was not a chance she was willing to take. Too much had already been taken from her and she knew there was still more to lose.
