Although Gwaine faced execution when he fought with a thug who was posing as Sir Oswald to kill Arthur, Arthur's willingness to vouch for Gwaine's nobility of heart convinced Uther to lift the threat of execution to simple banishment, Gwaine admitting to Merlin before his departure that Arthur wasn't like other nobles, and commented to Gwen that he understood why she had turned him down after he heard her talking about Arthur. Despite the threat of exile, Gwaine returned to infiltrate the melee the next day to assist Arthur in fighting the two thugs who sought to kill _him_, Arthur subsequently allowing Gwaine to claim victory in the melee even before he learned who Gwaine really was. <sep>, Pronoun: him <sep>, A: Arthur <sep>, B: Gwaine
