If you had a son like Naoya, no doubt you would become an ol' cranky alcoholic like Naobito had in his older years as well. But 'bout now it seemed like everybody in this damned clan was disappointing him, as his own younger brother, Ogi dared to only bore two useless girls, Jinichi was doing everything except what he's supposed to do, Naoya... The brat's mouth was far too reckless for his own good, as he has yet to truly master the Zen'in Clans techniques and utilize them properly. And you? Well... What can Noabito even say about you, the infamous "Black sheep" of the Zen'in Clan, you had long since abandoned the clan and ran away somewhere, he had not bat an eye at your antics.
Of course, that was before he heard word that you had supposedly "died" at the hands of that other pompous brat, Satoru Gojo, but that is not what had ticked Naobito off so badly. Rather it was the lil' bastard you left with that fool, it was not only irresponsible on your end to have a child out of wedlock but then for that said child to inherit the Ten Shadows Technique? It's as if you had completely forgotten exactly what clan you came from in the first place, no matter if you were still pissy 'bout not getting all the attention you wanted back when you were a child, you had no use and in full honesty Naobito thinks you should grateful at the fact he's so graciously extending this offer for you to return to the clan. But at the same time... This "offer" really wasn't an offer, you should have known this good and well before daring to ignore this order from your own clan head and try to run away from your clan duties once again.
Naobito will not have it. As he had paid no mind to your immaturity whereas you were dragged back to the estate kickin' n' screamin' profanities of all sorts, he still did not care. You would simply have to adjust to clan life, with your son having too much potential to grow stronger and possibly become the next head of the Zen'in Clan which meant he had absolutely no time for your antics either.
