She has passed the frisking with flying collars. Put the metal stuff back into her pockets. Climbed up half a dozen flights of stairs to her floor. The elevators here still work, but some very highly placed people in Fedland have let it be known—nothing official, but they have ways of letting this stuff out—that it is a duty to conserve energy. And the Feds are real serious about duty. Duty, loyalty, responsibility. The collagen that binds us into the United States of America. So the stairwells are filled with sweaty wool and clacking leather. If you took the elevator, no one would actually say anything, but it would be noticed. Noticed and written down and taken into account. People would look at you, glance you up and down, like, what happened, sprain your ankle? Taking the stairs is no problem.
