[How lucky! Satoru is so used to curses avoiding him whenever possible that he had been ready for an annoyingly long journey of searching for Sukuna — and had thought that Sukuna would make a big mess in the process, creating a bunch of work for him, since he seems to be the only jujutsu sorcerer on this train. But as Sukuna has so graciously delivered himself into his hands, it looks like Satoru will be done with work long before dinner. Nanami would be proud. Sukuna is, perhaps, already too proud.

But there is an innocent bystander, which is not great, especially since Satoru's hold on her shoulders is currently keeping her in place, making him responsible for whatever will happen next. So he addresses his new "friend" first, pulling away his arm and giving the poor woman an abrupt shove backwards.]

Sorry, I found someone new.

[Aka please hightail it out of here.

Then, to Sukuna, a smile not unlike the one he gave him when they first met.]

And you're still not following orders at all. What can we do about that...

[Why does he sound pleased over this? Because there's an easy loophole for forcing Sukuna to play by the rules! Hence a brief show of thinking about it, and then a snap of his fingers to show he has an idea.]

Hey, Sukuna. Wanna be my friend?

[Since Satoru has already established network communications with multiple people, somewhere in this car, a train door is now unlocking in dismay upon hearing these words spoken without any true intent.]
