Alright, I don't feel too comfortable bunnying your character, so I'll leave the interaction between the rhyfamily and your character to you. Feel free to bunny my character to get there.
After being explained the situation, Kaizah would saybe pretty simple and say something along the lines of "You can't just let those two just throw you around like that, go talk to them, now." He isn't the wordiest person. He'll of course come to support Hiro and when the suggestion of fighting comes along, he'll be all up for it.
