Sirius Black quickly left the restaurant and, with a long stride, turned around the side of it.
People were already waiting there—Fred, George, and Ron were leaning against the wall, each holding their breath in concentration.
Harry stood at the very back, but unlike the others, he did not look as though he were bracing for battle.
When they saw Sirius Black appear, Fred, George, and Ron all opened their mouths, seemingly intending to ask something.
Before they could speak, Sirius Black raised a hand in a gesture for silence, forcing their questions back down.
As though he understood something, Fred cautiously took a step forward, quickly ducked down, and poked his head around the corner.
A moment later, he pulled back and stood up, nodding to the group behind him. "Wizet and Luna have gone ahead! They probably can't hear us now! We can follow them!"
Just as the group was about to move stealthily, Ron realized something was wrong. "Wait! Are we really going to..."
"Like this..." He hunched his shoulders and stamped his feet. "Go after Wizet and Luna? Won't the Muggles here get suspicious?"
"And Wizet's magic is really good!" Harry voiced his thoughts as well. "Professor Moody praised him all the time before. Maybe we should just forget it?"
"Not bad, Harry! You're very alert!" Sirius Black praised him. An idea surfaced in his mind, and a sly smile spread across his face.
"Let's buy binoculars first, then cast a Muggle Confundus Charm. Wizet won't notice us, and those Muggles won't pay much attention to us either!"
Fred immediately caught on to what Sirius Black was planning. "Using binoculars is brilliant! As long as we don't follow too closely, we won't be easily spotted!"
"Not bad, Harry! You thought it through so thoroughly—you're talented too!"
