Teddy had been deep in conversation, the din of the Great Hall and the complexity of the topic (once again everyone was in an uproar about these Weasleys' Wizard Wheezes comms, as they were every so few years) that he did not detect the shift in the Great Hall chaos until it had properly exploded. He tended to know when things were going wrong but there were few staff at lunch and he'd been sleeping poorly.
There were those sudden excited shouts that only came when students were in a squabble. He turned to find his sister Lily, who had just arrived, her brown eyes large with worry.
"Fight," was all she said. He glanced beyond her in time to see Jack Dyllan jump from a bench, elbow-first.
Why was he not surprised.
He swept through the crowd of students gathering for a better view and with a few swipes of his wand managed to yank Jack Dyllan off of the boy. She was still scrambling at him, despite the magical constraints.
"Dyllan, dentention."
"You don't even know the whole story!"
"From the glimpse I got, you're getting one no matter what, now everyone, stop!"
The crowd that had encircled the brawl pulled away. Among them was Lily Potter, looking ill. She noticed the retreat of the other students and took a step back herself.
Teddy surveyed those gathered. As he spotted Maddie and Alex, he let out a sigh. "Okay. So... I can guess what this is about. Okay... First things first. Mr Greengrass here should go to the hospital wing. The rest of you, let's go have a private conversation, and once you're healed up Alexander, I will come speak to you. Are we in agreement?"
