Keeping his features composed, he knocked on his son's door before entering. "Freddy?"
The boy looked up with a nervous frown. "Am I in trouble?"
George sighed. He was rubbish at this. After all, he was still a kid himself. "You gave Professor Zabini a Fainting Fancy to get out of taking a test," he said evenly.
"And I had detention for a week! I've learned my lesson, Dad. I swear it!" Fred insisted. "I won't do it again."
The adult bit back a laugh. How often had he and his twin sworn the same thing to their parents? Too many times to count. Never did they actually mean it, of course. It was more of a promise not to get caught in the future- a promise they often failed to keep.
"All right. I believe you," George said, though he didn't. His son was too much like him.
"You do?"
"Of course. Weasley's honor," George said, sitting beside Fred on the bed. "Just look contrite when you see your mum and tell her I gave you a stern talking to."
Fred's face brightened, and he gave a crooked grin that nearly broke his father's heart. "I will, Dad. Don't worry."
"Oh, and Fred?"
"Yeah?"
"Next time, take the Fainting Fancy yourself," George advised. "Much less suspicious."
