Well. Of the other Slytherins in my year I could see giving one to Daphne except I don't think we could really trust Blaise and I don't think we could give one to Daphne and NOT Blaise. I couldn't really see giving one to Milli, even though she's one of the other half-bloods -- she's utterly dense, I just don't know if she's reliable. There's no way I'd give one to Teddy, Vince, or Greg. Draco and Harry already have them.

Daphne's one of the 'model students' but she doesn't like Umbridge at all. She just knows that if someone loathsome but powerful likes you, it's certainly going to be to your advantage if they continue to like you. Blaise, though -- I just don't think we can chance Blaise finding out that Hermione also has a coin.
