What's the point of repeating the Arata/Hikari/Renji story with Kaneki/Touka/Ayato? I mean, so far it's exactly the same; sister falls in love with a man that is not of the liking of her little brother, he reluctantly accepts him, sister gets pregnant and then they get married, the only reason I see it repeating is if they are supposed to change it, as in, Touka doesn't die, Kaneki doesn't become crazy and Ayato doesn't spend his life clinging to the memory of his sister
That’s precisely it, I think. Freudian stories=overcoming your parents. Kaneki, Touka, and Ayato will overcome the Arata/Hikari/Renji tragedy. They will live, I do think so (Kaneki’s the most likely to die of the three but I still don’t think that’s terribly likely). Kaneki should overcome the tragedy of the first OEK, and Touken should overcome V to not repeat the Kuzen & Ukina tragedy with Eto–aka live to raise their kid. The kid shouldn’t die either.
It’s another reason why I think Mutsuki, Urie, and Saiko should also be saved from this tragedy. Just passing on tragedy means the cycle will repeat itself–or, at least, it always has in TG. The tragic cycles always have repeated themselves after they claimed more victims. Why would we believe that the cycle would be satiated with Mutsuki, Urie, and Saiko? Someone needs to say No More. But to do that they need to face themselves as they truly are and work for it.
The world of tragedy needs to be destroyed and a new one raised up.
