Merlin and Gwaine have been the best of friends since Gwaine helped Merlin and Arthur in their first bar fight together. They hang out at the tavern a few times a month, insult Arthur and joke about. But in all seriousness, they really care for each other. Arthur, the knights and Marlin go to defeat a beast called Groc (made it up) on the outskirts of the woods, and only comes out at night. What happens when Merlin thinks all but him are unconscious, but really Gwaines as conscious as ever.
