Burt from O&D visits MDR and gives Irv a map so he can visit O&D.

The map is a forbidden object on the Severed floor, because Kier Eagan has decreed “render not my creations in miniature.”

After Petey left, Mark removed the group photo of Petey, Mark, Dylan, and Irving, to replace it with the new group photo featuring Helly R. He found on the back of one of the photos a map, drawn by Petey, of the Severed floor and various departments that he had found over time.
