I know some folks think Harry is going to take up Amoracchius. Others think Thomas will. But what about in Battle Ground? Thomas isn't likely to bounce back in a couple of hours, and Harry has the athame to use, so doubling up with Amoracchius seems unlikely to me.
So who else might wield it, if only for a night? I know no-on has to, but let's speculate on the idea that it's in town and they're going to need all the help they can get.
Michael is heavily injured. Murphy is heavily injured and also she'd probably be terrified. Daniel is living elsewhere so no second generation from him, and the other Carpenter kids haven't been foreshadowed for any action.
Charity maybe? Probably not Forthill.
Mac?
Marcone?
Imagine a scene where Harry's brought Amoracchius to the battle prep and left it laying on a table, and Marcone touches the hilt absently while explaining to Harry that all he wants is to protect the people in Chicago, and a faint glow emanates from the sheeth?
What other mortals are around that might take it up? Rawlins? Stallings? Rudolph? Mike the Mechanic? Agent Tilly?
