nice chapter!
i didn't play the game, so i don't know how much of the story is part of it, but it is very good written and i like the doublecrossing...
...dumbledore seems to be loosing his touch to reality, when he thinks that everything is ok in england, when even american news talk about it...i hope snape isn't a vampire in your story...just too greasy for that...and please let harry kick his ass...i mean, dumbledore said to treat snape with due respect, sooo a little bit of pain and broken bones should be appropiate...=P
