Talking about Half-Blood Prince from the Speculations...

I like the idea of Prof. Lupin being the Half-blood prince... I also liked Godric Gryffindor being the half-blood prince, which can be very realistic since Gryffindor is a very powerful wizard back then... But the fact that he's already dead makes it go down the drain... Anyways, still rooting for Prof. Lupin though...
