The Sickroom

Each of the floors Ben visits in the hospital were selected in relationship to Dante's Purgatorio. The former hospital had two wings; a west tower (5 floors) and the east tower (2 floors). In order to keep with the design director Drew Hall and production designer Mark Terry constructed, multiple sets of floor signs were created and the team used every floor in the hospital to represent Ben's journey.

After been has been chased through the stairwell by the entities, he meets up with Ester, Isaac, and Captain Miller. After a discussion, he loads a magazine into a pistol and hands it to Isaac who then chambers a round. The next scene is a long shot of Isaac again chambering a round in his pistol. If he had, in fact, inadvertently chambered a round twice, there should have been a distinct sound of a full cartridge hitting the floor.
