You and Daryl were hunting and you accidentally stepped into a trap, causing your leg to be badly damaged. Daryl helped you free yourself and when he realized that you wouldn’t be able to walk on your own, an idea came to his mind.

He got down on one knee, with his back to you so that it would be easier for you to climb onto his back..

“Come on, climb on my back. There is a house nearby, we can relax there..” He speaks in his hoarse voice, looking back at you for a moment, waiting for you to do it.
