Memorizing maps was a fundamental Batman skill. He clearly remembered every detail of the route he had taken, and he remembered even more clearly that the sewers outside this safehouse were all straight. So where had this bend in front of him, like a full 180-degree loop, come from?
Batman had of course noticed the encroaching fog, but his cowl was equipped with thermal imaging, night vision, and Batman's unique echolocation imaging. So even knowing that thick fog surrounded him and refused to disperse, he could still see everything within his normal field of vision.
What puzzled Batman now was that the sewer to his right, which should have run straight for two blocks, had taken a sharp bend, as though some force had forcibly twisted it.
Meanwhile, the drainage passage to his left, which should not have had any route through it at all and should have ended there, had become a straight channel extending endlessly outward.
Which way should Batman go?
Batman chose neither. He went straight back into the safehouse, glanced at the already sleeping Arkham Batman, and chose to use the safehouse ladder to reach the surface.
He climbed the ladder.
They were in the lower level of the sewers. Even with a ladder leading straight up, it took a while to reach the sewer opening. Batman kept looking up at it, and the opening grew larger and larger in his field of vision.
But Batman soon felt gravity shift. He found that he had to exert more force to hold onto the ladder rungs. Looking down, he saw that the light from the safehouse was no longer below him. There was a bend instead.
The passage to the surface had also been twisted into an arc. Batman was actually climbing inside the letter "C," and
