Despite him beating a dude the f**k up that ending made this surprisingly wholesome. Sett--or well Settrigh I suppose only keeps reminding us how much he loves his mom. Making sure to leave her some cash and kiss her good night like a good son. Let's just hope she doesn't ask to visit the Orphanage or to take her to the job one day.
Like I said before: Sett is one simple ass dude and that's easily his strongest point. No convoluted story involving bunch of other characters(yet): Just him being the boss of an arena, making money, beating people's asses, and taking care of his mom. A good character overall.
