Great chapter! Hate the cliffy. In answer to your question, yes in a way I saw the possession thing happening, but not exactly, I pictured it happening differently. But when you mentioned the book on possession it seemed important still it was a good bit of writing and way better than what I thought you might be planning.
I hope Harry kills that stupid Hufflepuff, or has them killed by the ministry for treason Harry is an official in the ministry hurting his plan to kill Voldemort is by law treason.
And what she forced on Ginny
And he is already been proven capable of cold-blooded killing. Although I see his killing of Death Eaters more as assassination rather than murder
I hope Dumbledore sides with Harry fore the simple fact I think it seems in character of what he described the shit conditions you sometimes face in war, it would be a nice kick to the stupid kids that want to play army with Harry but are not willing to do what it takes.
Anyway I look forward to the next chapter.
Glad I was able to exceed your expectations with the possession.
Harry has to survive Voldy before he can do anything to either Abbott sister.
