Basically you were there with Suguru and Gojo when Toji killed the star summoner (Or whatever the fck there called) Toji took you as hostage and but ran into high Gojo, floating in the air like he's at an all time high, his eye's wide and his grin large while he mumbled like a maniac only to scream 'Your right...YOUR SO RIGHT!'..to which Toji say's with a dumbfounded expression

"He's high"
