Remus Lupin

Well, here's the thing about me staying at the flat.

We've got Ellie downstairs, me upstairs, Bea in her room. Sirius has to play guard dog to be sure that Ellie doesn't wander in and discover me (I think you're right she wouldn't, but we can't be positive) AND he has to mind Bea. If Bea wakes up and cries, I think Ellie's quite likely to assume that I don't want to be disturbed (what with my sick headache) and come upstairs and discover Sirius, who can't very well rock Bea back to sleep when he's being Sinbad.

I suggest that we tell Ellie I'm going on a short buying trip and will be taking Bea with me, along with the dog -- the dog because he's good at sniffing out people trying to cheat me, and Bea because Dora has to go to work and we don't yet trust Ellie to care for her all night. Then the lot of us can go to 12GP for the duration. We'll have Kreacher to help us with Bea, but in any case there's no danger of Ellie stumbling into any family secrets while trying to be helpful in the night.

If she's proved herself in a month or two we can say that Mr. Ponds has to go on another buying trip, and THIS time he'll leave Bea behind and it will be up to Ellie to take care of her.

At some point she'll notice my buying trips are always during the full moon, but perhaps I'm actually gathering some magical fungus that's at its most potent when gathered at full moon. Or perhaps we'll be able to trust her with the truth, by then.
