It would probably be viewed as dishonorable, but if it meant not getting smashed to smithereens, it would be worth it.
Sir Robert gets up and holds his sword with both hands, keeping some distance between him and Thrall. Thrall lifts his war hammer high in the air. Rather than dodging, Sir Robert jumps toward Thrall and stabs him in the armpit, finding a weak spot in his armor. Thrall grunts and swings his war hammer. Sir Robert rolls forward past Thrall, spins around, and attacks Thrall's hamstrings; this is another weak spot in the armor. Thrall cries out in pain this time, then falls to one knee.
Sir Robert continues his attack, and even though Thrall is on one knee, they stand at about the same height. Thrall parries Sir Robert's next blow with his war hammer and tries to stand back up. Sir Robert kicks Thrall hard in his knee, causing him to fall down again. Then Sir Robert puts his sword close to Thrall's throat. After a moment of hesitation which seems like forever…Thrall finally yields. Sir Robert helps Thrall up and shakes his hand. Then he raises his sword in the air and looks at the crowd, which is cheering in excitement. Sir Robert leaves to take his armor off and prepare for the closing ceremonies.
Varys starts asking you what you think Sir Robert will ask for from the Governor. As winner of the tournament, he'll be granted a boon from the organizer. Most men ask for Gold, titles, land…whatever suits them. After considering all this, you reply, "I'm not sure; you never know with Sir Robert Gale."
Varys puts his hand to his chin and thinks for a few seconds. "Hmm, maybe he'll throw Gold to the crowd again. I'm going to try and get closer to the front of the arena. Are you coming?"
