The Prison

After passing through the first set of vents, head up a long staircase and into an alcove to find Statue [1] hidden in the dark.

After opening the fridge, follow the Nome that runs out from behind it to the right, through a hole in the wall, to hug it near a lantern. This is Nome [1].

After passing the first eye that turns Six to stone, climb the mesh boxes to the upper level. Instead of heading along the upper level, follow the top of the boxes to the right and drop down to another section. Crawl through a mesh box to find Nome [2].

In the same section of the prison with Nome [2], climb to the upper level and follow the prison cells to the left to find an open cell with Statue [2] in the corner.

After Six climbs the file cabinets and jumps to turn the power off, squeeze through the un-powered bars. Check the left side of the area to find Nome [3] in a cage. Release the Nome and follow it back through the bars and hug it next to the file cabinets.
