Jules was so completely stunned by this kid's selfless kindness that his mouth almost fell open. At the last moment he kept it from happening, which was good given his fangs would probably have scared Shion. Finally he just shook his head.

"We all die some day, kid, but this isn't my day. And I'm sure not going to die because of something as pathetic as quicksand. It's not going to be the one to put my name on it's kill list."

That would be beyond humiliating for one, and for two, he can't retaliate against quicksand. He started working at his waist and eventually managed to get the buckle of his weapons belt undone despite the sand glued to it. A quick toss put it within Shion's reach. It was followed up by a knife.

"Hopefully the leather is strong enough on that. Jam the knife through the belt buckle. Make sure the blade is angled toward me and the hilt toward you. Get it down as deep as you can get it. Just make sure I can still reach the end."
