Should we be rescuing Rio...? We could kidnap her and find... I don't know. A train station or something. A lot of apocalypse movies feature train stations... We're better off looking for actual signs to read to discern what building is what.

[ This sort of looks like the apocalypse. Kido really doesn't have much to go on in situations like these, outside of things she's seen or read. A train could take them away. If the trains don't run, there's rails they could follow to get Rio out of this situation too. ]
