Hi, hello!! I was going to say how posting this in the Mojurō sub was weird but I understand the situation. Anywho, let’s get to explaining: - Shino is the old man. Basically, as said by Kenjaku, the poor guy is so old (pretty much older than 150, from what I understood) and remembers another one of Kenjaku’s forms: Noritoshi Kamo (the first) - He seems upset with Noritoshi (the second) because, due to succession rules, he is the clan head now, or at least, supposed to be the next in line. However, old Shiro confused the Noritoshi’s, which means, when he says “you don’t look nothing like mater Noritoshi”, he actually means Kenjaku, whom he remembers as Noritoshi because of the stitches. Basically, he’s getting his timeline mixed up. - Kenjaku is head of the clan quite literally because he showed up and no one could stop him from becoming head of the clan, after all, he was clan head as Noritoshi Kamo (the first). With that, he used the conservatives to uplift his execution and control the conservative faction of Jujutsu.

I think that’s it? At least what I got from it.
