Souji would rather not talk about things that are this important to him when there's an event going on. It's clearly messing with them--or at least with James. Souji hasn't noticed anything strange in his own behavior, but it's possible that he wouldn't; James seemed unaware that he was acting particularly odd.

He looks over at James, trying to gauge whether or not there's any point, before deciding that even if it does turn out to be pointless, it will at least make James feel better. So he relents.

"...Okay."

"...Okay."
