[Tilting his head, Satoru makes a humming noise, as if considering Dimitri in a new light. Despite his seemingly excessive tolerance for annoying people who invade his personal space, Dimitri has a good (and perceptive) point about Satoru's potential motives. He isn't far off from the truth behind Satoru imposing himself on his fellow passengers, after all.

Then again his willingness to accept Satoru regardless is still a little weird. Satoru doesn't have a whole lot of people around him who endure his brand of friendship without complaint, considering he is extremely irritating at times. Most people prefer to be rid of him, or at least eye roll at him frequently enough to risk eyestrain.

So maybe there's potential here...

He decides out loud:]

Okay. We can be friends.

[He wasn't sincere before, but he (kind of!) is now. Him and Dimitri, bffs for life from this moment forward.]

I got some things I need to do [aka dangerous "friends" he needs to hunt down] but look me up sometime. Satoru Gojo. I'm a good guy to know if you end up in a pinch.

[Text him sometime, Dimitri! Or don't, and he'll text you anyway...]
