It caught Toge's attention, briefly, but Shinjiro's body language and words were pretty clear - he didn't want to discuss this. He could understand. There was plenty he didn't want to discuss, but would if he he could take the burden on himself.

It wasn't even that, it was trying to prevent a disaster, but going back briefly, I didn't remember while I was there. So the consequences were still the same.

He was still pretty nonplussed about the personal consequences of the event. What he dealt with didn't matter in the grand scheme of things.
