"Going to have to work on your people skills, Goyle," Harry said, not missing the barely suppressed growl in Goyle's voice. It gave him a quick flash of satisfaction that that much hadn't changed at least; however much Gregory Goyle had changed in appearance he was still just a step up from a troll personality wise.
Since Harry wasn't sure how to answer that question, he ignored it. He was here to make sure Goyle knew he was being watched, and if he stepped one foot out of line there'd be Harry to deal with. "How are you finding your new position, Goyle? Having fun yet?" Maybe it was a little mean, since he was pretty sure this wasn't anyone's definition of fun, but he wasn't above a little meanness when it came to a few particular people.
