Brings clarity to Harry

I seized the hilt of Fidelacchius from where the Sword had fallen. As my fingers closed around the weapon I realized several points of cold logic, as if having them explained to me by a calm, rational, wise old man who was utterly unperturbed by my rage.
First, I realized that I was now alone on an uncharted island in the middle of Lake Michigan, with nothing but madmen and fallen angels for company.
Second, that I still had the coins and the Sword that Nicodemus had been after-and that he was still going to be after them.
Third, that the Denarians were sure to be really ticked off, now that I'd taken their real prize from them.
Fourth...
The ground shook, as if with the impact of a heavy foot.
Fourth, that since I had confounded Summer's attempt to track me via use of the little oak leaf pin, Eldest Brother Gruff had probably been waiting for me to use fire magic in battle-the same magic that I had entwined with the power of the Summer Lady two years ago at Arctis Tor. It was the most probable reason why Mab, the most likely suspect for messing with my head, would have taken my blasting rod and my memories of how to use fire magic in battle-to prevent me from inadvertently revealing my position to Summer every time I got into a tussle.
Only now that I had, Eldest Gruff was probably on his way to visit.
And fifth, and last, I realized that I had no way to get off this stupid and creepily familiar island-unless I could get down to the docks and to the boat I'd come in on.
I still burned with the need to strike back at the people who had hurt my friend, but the fact of the matter was that I couldn't strike back at them and survive-and if they took me down, I'd only be handing them weapons to continue the war Michael had spent a lifetime fighting to end.
My only option was to run. Realistically, even escape wasn't looking likely-but it was my only chance.
So I slid the Sword back into its scabbard, oriented myself toward the run-down little town where we'd first come ashore, and ran. Fast.
