Great start to the story mate, I do like how Harry reacted, a lot more calmer. Good, no more Lucius thanks to Harry. Harry was right - it was better to kill them if you couldn’t get any information from them, instead of leaving them alive to commit more crimes and cause more deaths.
But how did Harry learn Occlumency?? His lession with Snape, didn't help him.
Poor Harry, I wonder what is going to happen to him?
