Sky and Water

"Blood of the friend, forcibly taken, you will resurrect your ally." Voldemort is resurrected. It doesn't go exactly like in the books. This is what happens when I read a bunch of 'good Voldemort, evil Dumbledore' stories, and then try to imagine what it would actually be like for a good Severus Snape in such a universe during the 13 years spent alone at Dumbledore's side.
