Slughorn was fabulous, and Fenrir Greyback has tickled my mojo. He's so sexy in a murderous paedophilic way. XD! I didn't like Romilda Vane much, she reminds me of Bellatrix. Rufus Scrimgouer was a little annoying, but I sense there's a whole lot of backstory behind him.

Ships - Remus/Fenrir! :D HBP has also awakened a slight interest in Snape/Draco for me, and restrengthened my Snape/Harry obsession. :D
