During the Shibuya Incident. Gojo met Geto...

Geto: "Hey, Satoru."

Gojo: "Huh?"

Geto: "It's been a while."

Suddenly, nothing has went through Gojo Satoru's brain at all.

Gojo: "Huh? Who are you"

Geto: "G- Geto Suguru."

Gojo: "Who the hell is that"

Geto: "I-It's me... did you forgot?"

Gojo: "So? Who are you?"

A silence...

Geto: "Riko-chan"

Gojo: "No way you're her!"

Geto: "You damn insane-"

Gojo then puts out Geto's head.
