Bill nodded. He really did believe Harry meant well, but he was old enough to know that good intentions and what really happened weren't one in the same. "I know," he said simply, sipping at his tea. "And I promise not to get too mad if you do mess up." He smiled to soften the words, because Harry was family too, and he knew that the blame would be on both parties.
"Good, she might listen to you," Bill said, and some of his exasperation from earlier leaked into his voice.
He smirked at that. "So long as you don't arrest me for assault," Bill said, only half-joking. When it came to his family, there was little he wouldn't do while trying to protect them despite his wholesome upbringing.
Especially if you got on the wrong side of his temper at the wrong time.
