Wilbur had made Jack proud, the old boy was showing some initiative for once. He had wanted to sit back and see what the Tortoise would do. And he did not disappoint. But Jack did not trust the skeleton in the least. It was out of their hands however. The news chopper was getting every second of the confrontation. Jack thought they handled the situation as delicately as was possible. Even if the skeleton did something, the blow back should be minimal. Still, best to move on carefully. Jack holstered his pistol and sheathed his sword, raising his hands in a calming gesture. He did not try to mentally influence the skeleton, he could not know how the being would react to it. Instead he slowly walked toward the skeleton, hands raised to show he had no weapons. 

It wasn't completely true. His wrist mounted blades could snap into place with a gesture, and even without blades, his hands and feet were deadly all on their own. The fae steel should be enough to hurt the skeleton but he couldn't be sure how fast the man would regenerate. Strange to think of the skeleton as a man, but he clearly had intelligence and emotions. Humans may have seen creatures like him differently, but Jack was used to dealing with people that did not look like people. Jack walked slowly forward, gently gesturing to the officer and his captor, "Please let the man go and let me retrieve him. I swear that you will be treated fairly and humanely if you remain peaceful. If you'd like, I can find you an advocate for your case." Perhaps he was a subject of Lord Koschei, the Lich King of the Winter Waste. The king was one of several supernatural leaders who had a public presence. He was currently engaging in a land dispute with the Russian Federation. The Skeleton had several traits similar to a Revenant. Koschei might be willing to provide an advocate if the man turned out to be one of his citizens. Those were all questions for later however. 

Jack stopped just out of reach of the skeleton, holding out his hands to receive the officer, "I give you my blood oath as Vassal to the Winter Court. I swear it on my honor and my life. Release the officer and you will not be harmed."  An oath thrice sworn was as sacrosanct and unbreakable as any in the Supernatural world, particularly among the Fae. He hoped the skeleton knew this.
