At 8:13, the register called Holly’s name, and every chair in Room 12 scraped backwards by itself.
The silver wing in the caretaker’s palm flashed tomorrow’s date, then folded into a tiny blade of light. On the whiteboard, black letters crawled over Mara’s fresh name: Holly Downey. Pending.
Orla stepped so close their sleeves touched. “Absolutely not. She’s sitting beside me, and I’ve only just got my brain back.”
The caretaker looked at Holly. His badge, usually blank, now read Mr Voss. “Your mother built the first register to save erased pupils. Correction twisted it. I kept silent so it couldn’t count my voice.”
“Where is Maia Finch?” Holly asked. Her throat scraped on the name.

The Miscalculation burst from the board in a storm of red crosses. “Inside every wrong answer she tried to protect.”
⁂
Holly wanted to run at it. Instead she looked at 9C: Jayden gripping his ruler microphone, Bea holding Tamsin’s hand, Leo’s map-lines trembling, Nyla staring at the empty space where her brother should have been.
Mum always said show your working.
Holly took both Bone Keys from Orla and pressed them into the paper register on Mr Tafadar’s desk. “Sir, take attendance properly.”

Mr Tafadar’s hand shook once. Then he clicked his pen. “Holly Downey?”
“Present,” Holly said.
“Orla Quinn?”
“Present, iconic, traumatised.”
Names flew around the room. Mara Quell. Leo Marwick. Nyla Venn. Arun, Sana, Priya, Milo, Bea, Tamsin, Jayden, Jude, Reece, Callum. With every answer, a moth lifted from someone’s chest and became a number, then a memory, then a face.

Nyla gasped as a boy appeared beside her desk, blinking like he had only missed one lesson. “Rafi?”
He looked at her. “Why is everyone crying in maths?”
“Long starter,” Jayden croaked.
The Miscalculation shrank, its chalk skin cracking. “Mistakes must be removed.”
No one is corrected by being erased. We are corrected by being remembered.
Holly wrote the final name herself: Maia Finch. Present.

The classroom crashed into sunlight. Gears stopped under the floor. The cameras went blind. The Miscalculation scattered into harmless chalk dust across Mr Tafadar’s shoes.
⁂
For one breath, Holly saw her mum by the window, smiling with tired eyes. She touched two fingers to her lips, then faded into warm gold, not gone exactly, but safely remembered.
Mr Voss swept the chalk into his bucket. “My contract ends here.”
“Do caretakers get achievement points?” Orla asked.

“Only for clean corridors,” he said, and winked.
Weeks later, Room 12 was loud again. Ben and Geri appeared in Holly’s maths presentation as “statistical cats”. Jayden hosted Maths Island. Mr Tafadar pretended not to laugh.
Orla nudged Holly. “Same seats next year?”
Holly looked at the register, where every name stayed ink-dark and ordinary.
“Always,” she said.
