Re: Theo/Sirius.
Those are the yet to be answered questions upon which my hypothesis rests. That is to say there is no clear cut answer, but I believe it to be true. If not in it's entirety at least in part.
I don't know about grace, but Draco is far more to the point and blunt than I am. Isn't it funny? Now that I think of it, had my father managed to produce an heir when his peers had done the same, you and I would have possibly gone to Hogwarts at the same time.
How much you actually know about what happens would ease my concerns. I am worried by how you may react to news you may not wish to hear. In war and it's battles there is more bad news than good, as it were.
