Only time will tell if this will do it, because, sadly, Draco is adlibbing like mad in my head, and refuses to be the ass we all love to hate in this story...
Hmm, almost sounds like this one used some of his father's money to buy a functional brain. This could make life interesting for all around him, and rather more challenging for his father as I suspect -this- Draco would want to know more of just why his father was attacked.
