Last Resolution (слэш)

After the events of Small Favor, Harry is rattled on how easily it was for Nicodemus to break the Accords. He has come to realize how fallible they were and thus the danger Chicago was in. Thus the danger Marcone was as its protector and Baron. A little reluctantly he goes to Bob for advice for what he considers an insane idea. If anyone could know if it would even work without talking to the Sidhe, would be his intellectus. Bob confirms that the idea would theoretically would but it would be the first. No one had ever bound another to a vanilla mortal in the way he was suggesting. It would require a lot of time, magic, and a hell of a ritual. But in theory, binding himself to the mobster would give Marcone some protection from the supernatural. They wouldn't know the side effects beforehand though.
So with that in mind, Harry goes to the man and makes his case. For the sake of Chicago, and maybe to a small extent, for Marcone's safety. After getting a second opinion from Gard, Marcone agrees.
