The clerk was so taken aback that he remained silent. His eyes kept moving between myself and Bellatrix. The fear he had before, was now amplified at the possibility of a battle in his shop. One I wanted to prevent. Since I got what I needed, which changed my plans going forward for Draco, I wanted to help in some way. He was under tremendous stress that he could break. While I didn’t like the idea of sitting idle to whatever this vow was for, or even helping a plan for Voldemort.. Draco didn’t deserve to be in the middle of it. Not when he was that terrified anyway.
