In The Air: Explosions, Chapter 4, Part 2

The city guard captain did not keep Jake for long. There was not much information for him to add that would help. Reports were sent and the city put on alert to search out for a possible terrorist. With the risk of explosions and the security clampdown, Jake just wanted to get back to the comfort of his room. He missed the mundane life he was accustomed to. Perhaps being a Fall Guard would be more stressful than he was expecting.
Jake continued through an alleyway leading to the central transport hub. After some steps down he heard a motion behind him. Before he had a chance to turn around, something metallic was pushed against his back.
A barely audible voice whispered "Don't move."
In surprise Jake rejected the request and spun around, "It's you," he gasped, "the jumper!"
"Leto" was her paused reply, Jake frozen in fear of the gun now pointing at him, "And I suggest you don't ignore my warnings a second time."
