Last chapter. The Heaven's Wing

Douklan points out what he found, and then rejoins Mercer at the door. "That's just further confirmation that the dog was infected a few days ago. Who knows how long a creature can survive with...whatever this is. But rabies? Dogs without water? Can't survive more than a few days at most." He looks at Mercer through their visors, not because it's particularly directed at him when they're talking over suit radios, but because he's closest and so he can see a reaction. "So either the dog got infected and they trapped it in here as a kind of quarantine, or the dog was in here, got infected, and no one ever came to let it out. How much you want to bet it's the latter, and the station is all ripped up because the dog wasn't the only one to get infected a few days ago?"
