Thanks for reading and taking time to comment--it's appreciated.
I'd never written Harry/Draco before, so it's good to hear that the pairing worked for you. I actually worked on several scenarios of exactly 'what' Snape was inside of Draco, and at one point I thought of him being the Horcrux, but then that got horribly complicated, so I ditched it. See, we were thinking alike, at some point.
