SPOILER!!!!
He goes to help defeat the evil dude, but he doesn't talk to him again. He does send notes and gifts to Soun and his nephew sporadically, he doesn't do send them to his brother because he just lights them on fire (he sees it like Siryu claiming he's not taking care of Soun and their kid good enough)

Novel readers please spoil for me will the brothers speak to each other again?
