Heiji was pretty well off, all told; his bizarrely excellent memory and earlier efforts guaranteed that he had a good idea of the layouts of most rooms. 34 steps to the Cafeteria, and he was in, 55 steps to the... chair?

And someone had rearranged the chairs. Well, that made sense; they were probably running from robots when they did. That did make navigating rather more complicated, though.

Goddammit. Maybe he should just back out and try Plan B.
