Eames searches for clues in this strange amalgamation of locations. He doesn't know the layout to this maze and the numbers on the doors yield nothing new to him. It's the same secrets he keeps buried down here -- at least, they are until he rounds a corner and discovers Arthur standing in the lobby.

Usually, Arthur stands faceless in his dreams. He's a projection that represents the other half of his brain. Sometimes, Arthur exists for nothing but to act as the devil's advocate. Sometimes, he's an ally. For a predictable man in reality, his projection is terrifyingly an unknown.
