The only problem with that plan is my going off to the Ministry in the middle of the night.

I know we want Ellie to take care of her eventually, but I don't know that it's a brilliant idea, leaving her in the night while she still seems to feel so unsafe and skittish.

Are you sure you couldn't just say you're coming down with one of your sick headaches, and then go off to bed for the duration? You could lock the door. It's not as if she's going to want to barge in on you if you're ill.
