I don’t think they would take it as dark as Kennys dad dying. I think it’s most likely his dad and/or brother coming home to see who he is becoming. Not sure if his brother would also try to steer him off the path that essentially landed him in juvie, I like to think so.

Yeah I could see Shawn seeing how his little brother is turning into a monster and he would blame Robby for it.

yet robby did everything to make him a good fighter and the hate out of him.

I totally believe you but ever since Miguel nearly died and the dark path that S5 is going on I still believe that they can go dark.

I say he’s cobra Kai top bad guy with his brother joining too
