Bolero has finally able to find Ernest and Celestine (although he doesn’t know HOW Ernest got into this size yet), and tries to explain what happened to him, but he’s unable to speak aside from squeaking (he’s a mobini mouse, after all), and Celestine never interacted with such before, so she wouldn’t be able to understand a thing. Maybe Bolero will find other ways to communicate, such as using pencil and paper (he still has enough intelligence to know how to spell). But even if he did explain, the trio would still need a way to revert all of this sudden happenings, and it will probably take a while to do so.
