I love so many interpretations of Snape and Harry, but have such a fondness for the way he's written by Alchemia Dent & Bugland. Sometimes I find it hard to read because it makes my heart ache. But I can never put it down. Have you ever read Pigfeathers? It's really fabulous.
I'm curious what you found horrifying about the idea. I'm pretty sure I can guess why it was intriguing. ;D
