[Hina squeaks excitedly! If she could speak human languages, this would spoil the later realization in the TDM, but as it is, Frieda and Rinku will not be able to tell that Hina is happily declaring that she (thinks she) will evolve into Saya.

Rinku brings up Golbat on the app (pointed at Frieda, so Karpje and Mecchan can't see the screen to tell Hina she's wrong) and shows her, then flips to Crobat.]

She's got two evolutions! The first will happen as she gets stronger, and the second one says it happens with friendship. Which means once she evolves once, I bet the second will happen in no time!
