"As you know over the summer The Dark Lord gave me an assignment, you helped me with the first step at Borgin and Burkes. I have decided, however, not to complete the next step." Draco held up a hand to halt Theo’s words as he opened his mouth to speak. "Let me get this all out first - my mother made an unbreakable vow over the summer to keep me safe during the task I was assigned. Which means I can't just forfeit without consequences..

I thought you should know."
