"And we're back to you not taking a joke, because did you ever do anything about that before you let it blow up in all our faces and you storm out like some indignant prick?" Because Fred couldn't think of anything they'd done to Percy that they hadn't done to Ron, or wouldn't have done to anyone else.
At the last bit, Fred opened his mouth, then closed it, then opened it again. "No, you're right. Thank you, Perce." Oddly enough, it didn't sound at all like he meant it. Was that sarcasm? Definitely. Would Percy expect anything else? Fred had a sinking suspicion that he wouldn't. "Thank you for making mum a basketcase, and dad feel guilty. Thanks for staying away when Bill needed every support he could get. Oh, and for not giving a damn about what I just said about George. Thanks ever so much for not giving a fuck that your brother could have died. That he was about an inch from a Avada and that someone else took it in the back for him. That's a real man you've turned into. Got your shield of hurt feelings to show everyone." He shook his head and took a step back from his brother, mouth tight - not even a joking, mocking smile there now. It wasn't a look that seemed even remotely natural for Fred. "Forget it. Stay away."
