In the Theatrical Cut, this chapter continues from the perspective of Conrad if he is available, and Alex if he is not. In the Curator's Cut, it continues from the perspective of Julia. The first room on the left contains Secret #14: Guard Duty Roster. For the next item of interest, enter the room at the very end of the next hall, before the exit which Conrad or Julia stands by. Take a left turn into the bathroom area, and take a right turn to find the stalls. In the stall at the very end of this row is a letter that can be picked up and turned over for Secret #45: Private Reed's Letter. Return to the main hall and proceed down the narrow path to continue.
Before passing through the exit where the next character (Alex by default) waits, take a left turn to find a small surface with a book atop it. Pick up the book and make sure to flip through its pages for Secret #7: Engineer's Logbook. Continue walking forward until you reach a large open room. Head to the back of the room and take a left to find a table where another book can be picked up. Flip through its pages for Secret #11: Journal. From there, walk to the far-right of the room and stop in front of a cabinet. Inside is a very well-hidden Picture, In the Offing, indicated by a prompt that should pop after stopping in front of it. Walk toward the screen to find the exit and continue walking to trigger a scene.
If Fliss and/or Brad are still with the group, they will get separated from them here regardless of the choices made; while Conrad can warn Fliss to improve their relationship slightly, she will inevitably get caught by Danny. This new development in the story leads into Caskets in the Theatrical Cut and Danny in the Curator's Cut.
