From Inside the Grey House:
Charlie shook his head and shrugged, not sure of what to say. Instead of trying, he unbuckled and unzipped his pants, pulled off the ripped pair and started putting on the new pair. Natalia didn’t comment, deciding to pay attention to the road instead. She was able to reach Jeffery’s apartment quickly and without incident. Once there, she pulled out a new chloroform cloth from her backpack and placed it against his nose and mouth. She left it there for a few minutes, then put the cloth away.
