I wonder why Professor Carrow was researching the Dementors? I didn't think there was much that wasn't known about them, just that they enjoy swooping around and making people depressed.

Vince was talking about that earlier, the bit about two Sirius Blacks, and at the time I thought he was just being thick. Oh, but the potion must have been strong if it made Professor Carrow see that!

What are you doing at Hosgmeade tomorrow? Spending time with anyone in particular?
