He is chilled and easy going , I wouldn’t say he has had a downfall officially. He is a flawed human being like any one of us. Cockiness is inbuilt in him that shows. But he is street smart and definitely deserving to win the game. He can control his mouth a bit through unnecessary comments. Someone needs to tell him that. Also its like the fag end of the show, everyone’s mentally tired too.
I’d say its better to have ups and downs in your journey graph , which shows that you’re doing something good and bad both, than to have a clear straight line .
