Wow! Wow! Wow! That was really intense. I loved how it progressed : at first, Harry has a potentially dangerous problem with his magic, then he is manipulating Severus to have his (wicked) way with him but at the end, he is getting power from so many people it's frightening to imagine what would happen next. The fact that he seems to be oblivious to how wrong this is makes the story even more chilling. Wonderfully written.
