I'm not a follower or Pretty Cure, but I saw once an episode of one of the series (post Heart Catch) where this happened:
The girls from that particular season are already a team (so it's not an episode from the start of the season), and they're hanging out at school. Then one of them (the smart one of the team) gets news that she was accepted at a very prestigious and exclusive school. She had applied to it months prior, and said "girls, I applied to this school before we became friends, and now I don't think I should go because we're pals and a team".
Then the other girls encourage her to take the oportunity and go, because academic achievement Is important and chances don't come often.
They say things like "it's not like we're not gonna be friends!", and "wow! You're so impressive! Totally go!, and "no matter what, we're gonna be Pretty Cure!"
And while they encouraged her, the fairies they have (I think they resembled stuffed animals) went "eeeeeh? You're gonna leave?"

And right after the smart girl leaves, feelings better because her friends didn't get mad, all the other chicks hide behind a corner and start crying.

Anyone knows the season and episode number?
And the name of the episode, if possible.

Thanks.
