Thank you for all your reviews. I'm glad you're enjoying this so much.

I always thought Draco was underused in Canon, he had the potential to either become a good villain or turn to be an unexpected hero, instead they just painted him as a coward who couldn't decide which side he was on.

But he had to be in Slytherin for a reason, the house of cunning, both his parents, seemed quite inteligent, so one expects him to be too. So I would expect that he could indeed plan something and have the patience for proper execution, but at the same time he is still a spoiled teenager, very much influenced by his father and angry that his position and status had been lost, so I could also see him feeling justified at what he was doing. Really believing Harry deserved to be punished.
