"I'm afraid there isn't like to be a next time, though if you wish to visit me here, I don't mind a quick flash," Bob replied with a chuckle and Harry said, "No. Really, no. Bob." Bob rattled a little bit but stilled and then Harry turned his attention back to Keara who apologized in a way but not really. Sure, if it wasn't just a gag skull, she wouldn't have taken it, but the point was, she took it.
"It shouldn't really matter if it's a gag or not," Harry said, "you snuck into a professor's office and took something from it." Because in the end, that's what it was. He could just imagine what Murphy would say about this and he felt a little sad, knowing she wasn't there. He'd gotten used to being around Murph so much.
"I'm taking twenty points from Gryffindor, you're serving detention with me," he said calmly, "And gag or not, seriously, don't take things from a professor's office. You don't know what sort of trouble it'll bring you."
