Shen Qi and Florges were great heroes who had saved the futures of all the Flabébé. By comparison, Flabébé only had to hide for a while and temporarily go without seeing her chosen Pokémon Trainer. That effort was insignificant.
"Should I get you an Everstone to wear?"
Wearing an Everstone could stabilize a Pokémon's current state and prevent evolution. Rather than the discomfort of forcibly holding back until they adapted to not evolving, it allowed the energy within them to be channeled more smoothly.
Shen Qi estimated that breaking through all the remaining Evolution Imprison would take three days, with another day set aside to check for any they had missed.
For the next three or four days, Alola's scientific community would surely still be focused on the research findings Lillie and the Aether Foundation had presented together. Professor Burnet coming to Melemele Meadow was unlikely.
Getting an Evolution Stone was simply a precaution against some other stimulus exciting Flabébé and causing her to evolve on the spot.
"Then... thank you for that too, Mr. Shen Qi."
Flabébé had concerns about that and shyly asked Shen Qi for help.
"No problem."
Florges needed rest and was in no condition to run around.
Shen Qi called Pelipper and Dodo over and asked them to visit Hau'oli City the next morning to buy an Everstone from a Pokémon supply store.
"Gujī?"
Dodo and Pelipper were puzzled by the sudden request. They had clearly come to help Flabébé evolve, so why did they need something that prevented evolution?
"Here's the situation. Professor Burnet... Flabébé... and that's how it is."
Shen Qi told them the story. "Flabébé hopes to grow under Professor Burnet's gaze, with her chosen Pokémon Trainer by her side, and show her a stronger form."
"Gaaah!"
Pelipper understood the feelings involved
