Thomas understands his role well enough to know that so long as the questions - and answers - are unpleasant, the floor is his. Olinger will step in after that dirty business is done, which is just fine with Thomas. The Mayor's aversions keep Thomas relevant, and necessary. He wouldn't have it any other way.
The lines of thought of the two cops surprise him slightly, though it doesn't show beyond a minor furrowing of brow. The difference between infected and dead means very little to Thomas, but he supposes some people feel differently.
"Killed," he says, without preamble. "A Washer from outside discovered Roccolini, recognized that the uniform might make the information pertinent. And valuable, more importantly," he adds, with a short scoff. His derision for the entire Ghoul nation is quite plain. "According to the junkie, Grady was shuffling nearby. He put the Chief down, and asked for a dozen cans of baked beans for his services. We can only assume they were out on patrol, and something went wrong."
Ah. Now here is where the Mayor likes to come in. All that bad news is out of the way-- what more can one need to know, really? The superiors have expired, in one way or another. Moving right along. The Mayor reaches into the pocket of his rumpled suit jacket, taking out the badge that had been removed from the former Chief's remains. He rubs it with its sleeve, but the metal is still dull, crusted over with gore. With his usual social awareness, the Mayor is totally oblivious to how distasteful this might be. He holds the Chief's badge out to Archer and smiles kindly. "So congratulations, Commander. You're Austin's new Chief of Police."
