Not make any more promises that might end up getting broken, not any more of these things he said that he could barely believe in anymore, even as he said them. He travelled alone these days and the thought of someone, of Jack relying on him... But too many always did, all the more people that he could let down. Again and again.

In the end he gave a nod, turning his head do took at Jack over his shoulder. "I promise." He'd somehow have to handle everything and probably watch it go wrong. "And, Jack. Take care of your heart, yeah? You only have the one."
