It was a little disturbing for his spell to be properly working, but he also didn’t want to just up and scold Potter immediately. He knew that there would be no point anyway, having seen just how much Potter fidgeted about during a normal conversation, so he wouldn’t even dare to think how much he could differ about during this.<br/>“But I need you to keep still while I do this, otherwise it won’t detect anything,” he stated, figuring that that was a fair thing to say to Potter, even if it might sound a bit harsh. It was incredibly important to Draco though, who really wanted to be able to pull this spell off, knowing just how complicated it was and how much concentration it took for him.
