[Ryoji knows that it's a difficult thing for Joshua to accept... Still, trying to cheer him up in any way is the only thing he can do right now. They're unable to really do anything about it for as long as they're here.]

You know, a little while back I talked with Castiel-san about fate and how The Fall was supposed to happen back in my world... He told me that the apocalypse was destined to happen in his own universe. And he also always thought it couldn't be changed, that it was all set in stone from the beginning... but they've stopped it. I didn't believe that it could be the same case with my world, even though Castiel-san tried to convince me.

But then that other me appeared here together with Minako-chan for those two weeks... and it turned out that The Fall didn't happen for that Ryoji, after all.

[That had a big impact on Ryoji's views and beliefs. It took him a while to actually accept and come to terms with all of that.]

So your world can't be off that bad. I'm sure there's also a way to save it.
