After finishing the conversation with Mr. Weasley, Harry turned around and saw Fred and George squatting in the dark corner of the stairway platform, laughing so hard they were out of breath.
"What are you two up to?" Harry walked over and asked, curious about what prank the twins were concocting again.
As for what Mr. Weasley had just said, Harry only half heard — he had agreed not to seek out Black because he had no time, as he was busy collecting Sweet Mallow leaves and had no time to look for Black.
Even if Phineas Black had come back to life...oh, Harry would certainly go to watch the fun, see how old classmates hit Phineas with a Stupefied spell.
Harry believed that even Dumbledore wouldn't resist secretly casting two spells, even though they were both headmasters of Hogwarts.
Hearing Harry's question, Fred gasped out, "Percy is having a fit, he can't find his Head Boy badge, but George and I thought it was necessary to give the badge a makeover."
"The badge now says 'Big Head Boy'," George added, "because his head is so big, don't you think?"
Harry imagined the funny sight of Percy wearing a "Big Head Boy" badge and laughed along.
"So, I heard you're being hunted by someone?" Fred said, putting an arm around Harry's shoulder, "What exactly is going on? I only heard a bit."
"There's someone named 'Sirius Black,' who used to be a devoted follower of You-Know-Who."
Harry chose not to say Voldemort's name; although he did not fear it, that didn't mean others wouldn't be affected by hearing it. He didn't need to show off his fearlessness this way.
"Now he escaped from Azkaban, and Uncle Arthur is worried he'll come after me, that's it."
"Ah, that's how it is," George and Fred replied in unison, "That indeed sounds cool — but, since you're being hunted, both of us thought we should give you something fun."
"What's fun?" Harry asked interestedly.
"Think of it as an early Christmas gift from us. You know, your idea helped us make a lot of money at school," Fred said cheerfully, looking around like a casual salesperson and pulling out a square, folded parchment from his pocket.
"We don't need it now, but we don't want this old friend to become useless," George explained, "Come over here, come along with the big brothers..."
They walked into an empty room, and George and Fred carefully closed the door together.
"It's a bit hard to part with this," Fred said regretfully, patting the parchment, with a look as if parting from a lover.
"But just now, we decided you need it more than we do, Harry," George said.
"Is this a magic item?" Harry asked interestedly, "I trust your judgment, you're the best pranksters I know... Did you get this from Zoko's Joke Shop?"
"From Zoko's Joke Shop?" Fred asked incredulously, making a funny face with his eyes closed as if Harry had underestimated him, "Explain, George."
"Alright, when we were in our first year, Harry, back then, we were young, carefree, and naive—"
Harry let out a 'ha-ha,' truly doubting whether Fred and George had ever been naive.
He remembered when Ron was very young, they had turned Ron's gift into a big spider as a prank, leading to Ron now having arachnophobia.
Furthermore, they had also burnt Ron's tongue through a prank.
One should say, there were no brothers more outrageous than these two.
Seeing through Harry's disbelief, Fred added, "Well, more naive than now—you see, we had a bit of trouble with Fitch."
"We set off a big dung bomb in the corridor, for some reason, the bomb really upset him—" George said.
"Upset him? Why?" Harry curiously asked.
"Because we hit his cat, that red-eyed thing," the two said in unison, "So he dragged us into his office, started with his usual method, you know, he loves cats intensely."
"He wanted to put us in detention and use our guts to scrub the deck..."
"Come on, Fred, that's not Fitch's line. He just wanted to hang our intestines out in the sun, not a pirate!" George seriously corrected.
Fred raised both hands and gave a flawless salute, "Alright, anyway, we couldn't resist noticing his file cabinet drawers, one of which was labeled: Confiscated Supplies, Highly Dangerous."
"You mean this? Highly dangerous?" Harry pointed at the parchment. "Okay, so you stole it? Right under Fitch's nose?"
"George threw another dung bomb, distracted him," Fred said happily, "I quickly opened the drawer, grabbed—this."
At this point, Fred patted the parchment in his hands.
"It's not as bad as it sounds, you know," George said, "We think Fitch never figured out how to use this parchment, but he probably guessed what it was, or else he wouldn't have confiscated it."
