He he will even get paid by Numloch just for making the attempt.
And yeah everyone's getting the shaft here. They don't know Charlie is a carnymancer. Charlie may or may not know they have another carnymancer on staff, who herself may not know the full plan or whose priorities may have shifted. Numloch and Delkey are both getting messed with, but one or both of them may discover the truth behind the ploy, and/or either of those sides might show up with unexpected reinforcements. I hope there is something in the contract for Charlie to actually help Homekey if something goes wrong.
