Well, we all know how this turned out.

I could see this a few seasons after the ending, but slightly change the ending we had. Misty all happy everything back to normal asks “So what happen to Opaline, did she get away?” Sunny looks to the tree and states she’s somehow trapped inside, some of the others comment that’s how it should be as Misty slowly walks up to it, and places her hoof on the tree. Noticing Misty’s demeanor, Sunny shushes the others placing her hoof on her back. Misty sadly says, “I know she didn’t care about me, but she was all I had growing up, I just wish she changed instead.” Cue the others giving her a hug, reminding her of her family. Sunny replies maybe someday, someone can get her to understand.
Maybe this could have been after.

She’ll likely slap the hoof away

I don’t know if it makes me happy or even more sad because it’s not canon and never be…

Slaps hoof

Well, I’m not that satisfied when she’s sealed away in the Together Tree.

I hope this happens. I want Alura to free Opaline and use Opaline. Then you have to save her.
