That..."The Worst, Most Despair-Inducing Incident"...? Er, I understand Enoshima-san set it off, and there were riots of some sort, but I don't really know all the details. That the world "ended", that she caused it to come to that state...that it was bad enough that we agreed to be locked away forever...that's the sort of thing we learned of, but probably she knew it was worse if we didn't know the exact details, isn't that so...?

[ A half-hearted shrug, as he readjusts his grip on his groceries. ]

...After all, not knowing is also a sort of despair, or rather she wanted us to be afraid of choosing the exit....
