Ok, so I may have noticed something that makes it seem like Daryl might be Lucille'd. So in the comics Dwight has a Crossbow that he uses frequently. He even killed Abraham with it. And he had a scarred face from Negan burning it with a iron. So here's what I think may happen.
He gets caught by Negan and gets his faced scarred so he has his trademark appearance. Then he stays at the Sanctuary with Sherry becoming a wife again, and Daryl is executed, so Dwight inherits the bow. Then he becomes a spy for Alexandria and the rest is history.
Tell me if you think I'm insane and need to drive the short yellow bus
