"Two busy men—what brings you back here?"
Mrs. Weasley emerged from the kitchen carrying food and looked at Fred and George seated in the dining room, her eyebrows rising slightly. She remembered that they had only moved to Diagon Alley the day before yesterday, supposedly into a hastily erected tent.
"We recently received some pamphlets from the Ministry of Magic."
"And we had a few special ideas."
Fred and George exchanged glances and said in unison, "We think everything in those pamphlets the Ministry handed out is rubbish—completely useless. So we're planning to make our own..."
"What are you planning to do?" Ron and Ginny came downstairs.
"We're planning to compile some pamphlets ourselves, ones that can actually help people. So we need Remus and Moody's help," George explained why they had come back for dinner.
"Didn't Anderson publish one?" Ron really could not understand what Fred and George were trying to do.
"Yes, but that's not what we need. We need something simpler, easier to understand, and more reliable..." Fred suddenly turned to Ron. "Why am I even explaining this to you?"
"This has nothing to do with you." George picked up the Butterbeer keg and poured himself a glass.
"You..." Ron was thoroughly enraged.
"Is that really necessary?" Ginny was puzzled. Sirius was doing something similar, after all—teaching people how to protect themselves and their families in these turbulent times.
"It's very necessary. Defense Against the Dark Arts items are hugely popular now. People are desperately looking for protection, and loads of wizards are putting out all kinds of useless rubbish to fool those poor idiots."
"At the very least, we can help them spend their Galleons in the right places instead of buying piles of worthless junk."
"You're not opening a joke shop anymore?" Ron asked suspiciously.
