"You see, I sent you to fight this powerful N2 (although maybe Yuki's stronger, who knows) sorcerer, because I was sure that his Sorcerer Supremacist ass wouldn't kill young sorce-... oh shit, Maki, I'm sorry."
Honestly Gojo taking a bet on Yuta and Geto's mercy would still make more sense if he couldn't teleport over and beat Geto's ass in under two minutes for whatever reason.
Also someone remind me, but the previous Goodwill Event happened BEFORE the Night of hundred Demons, right? What if we get to see that?
Yeah, the most telling indication of that was the scene where Geto is talking about the importance of capturing Rika and how their chances of winning against the combined forces of Jujutsu society are low, but with Rika the chance of success in 99%. Like, at no point does he acknowledge the fact that the other side has a mortal god in their ranks. It is not even just an insinuation that Rika could beat Gojo (pfft lol). His strength isn't really factored into the dialogue the way it should be.
