Jujutsu Kaisen S3 - Episode 8 | JUSTICE (Patreon)

Okay, so help me out here - How does Reggie know Kenjaku's name? Is it because he "went to" everyone like that member of the occult club and spoke to them when he gave everyone sorcerer abilities before the Culling Game? Does this mean that Higuruma within X amount of days got ahold of his ability and learned domain expansion within only that amount of time? I was confused at first because it showed his day to day life but remembered that they have a set number of days before having to decide to join the games or not.

Also, should we be concerned for him already? Domain Expansions trigger Sukuna, no?! Who is Fake Geto reporting to?!
