Gojo had gotten Yuji to watch him fight Jogo. Jogo had used his domain expansion but Gojo used his domain expansion to combat that and ripped Jogo’s head off.

Gojo: he steps on Jogo’s head. come on, tell me what your motives are.

Jogo: grrrrr!

Hanami: she uses her flower to make Gojo lost all will to fight.

Gojo: hm. That’s such an odd cured technique.

Hanami: she grab’s Jogo’s head and Yuji and runs off.

Yuji: don’t worry sensei! I can take him!

Gojo: it’s good at hiding its presence.
