"Of course I did, you idiot. Did you really think I'd leave without you?" She smiled and kissed his head gently, holding him still while Corin healed him. Sapphire was tired from her fighting and Corin was getting tired from healing Nathan's wounds, and poor Nathan was pretty much unconscious.
Sapphire did her best to make him comfortable. When all of the wounds were finally healed, Corin stopped to rest. "Oh, how awful. He must have been in so much pain..." She looked at him and then Sapphire. "He's going to be pretty much useless over the next few hours. His body was barely holding on when we got here. The energy in his body is gone. He needs to recover, so he won't be of much use in getting out of here."
Sapphire frowned and then nodded. "I have an idea, but you're probably not going to like it..."
And so it was that Nathan and Corin were put into a simple coffin and wheeled off by a disguised Sapphire. Somehow, against all odds, they managed to make it out of the castle undiscovered. As soon as it was possible, Sapphire let the other two out of the coffin and had Corin help make a stretcher between their two brooms. They'd have to go slowly, but they could fly to the next town pretty easily.
