You keep your pencil moving even after the academic assistant appears in the doorway.
That is the first thing you learn about survival in places like this. You do not flinch too early. You do not give people the satisfaction of watching your pulse from across the room.

“I’ll be back,” she says.
Nobody answers. She leaves with the assistant, the door shuts, and then the entire room exhales at once.
The noise comes back in pieces.
