Lyra had been up in the stands to watch the quidditch match, both as a lead up to their plan and with strict instructions to report back to Lucius on Scorpius' performance. The boy had comported himself well. He wasn't exactly a natural on a broom, either, which made his efforts that much more significant.
As the game broke up, and most of the adults headed back to Hogsmeade for a drink or up to the school for a chat with whichever teacher they were shagging, Lyra slipped away into the forest, where she waited for the children to arrive with her new toys.
It would be nice to have something shiny to play with. Lyra suspected Morgiana was getting Stockholm Syndrome. She'd stopped fighting her sister ages ago, and Lyra hadn't needed to change her wand's hiding place for weeks.
It wasn't long before she heard the sounds of an argument, and spells being cast about. That would be them. Lyra crept through the undergrowth toward the sounds so she could see what the fuss was about.
She was pleasantly surprised. Malfoy and Hutson had already got one girl petrified, and were rounding up the Potter kid as she watched. Lyra gave them a little round of applause as she stepped into view and pointed her own wand at the hostages.
"
Homo Leviosa," she said. "Come on, you two, unless you want to be caught."

We're all going here for a bit))
