So after the Nightmare night incident with Opaline stealing Posey's cutie mark, Misty felt sorry for her since she has been blank flank herself. And since Misty had experiences with making a False cutie mark on herself, she tried it with Posey and tried making it as close to her original cutie mark.
It's also "kind a" of a inspiration when Grapefruit-Face made a Crying Misty being Comforted by Posey, Based on something that I still don't like to looked back at. But now It's Misty's turn on Comforting Posey and helping out.
And Since then Posey is pretty much growing on me since and before she keeps being treated worse after that Episode and after the first Chapter since she had a bit of a good change of heart. The writers just keeps making her the Punching bag of G5 and it's kind a sad, Now yes she was racist and mean and pretty much being a Karen throughout most of the first chapter and some episodes of TYT. But she did apologized and learned her mistakes and yet she does have her moments that aren't her being a Bitch. And I think she's a better redeemed Earth Pony unlike Another Earth Pony Cough, Cough Sprout.
That's all I Wanted to make and there might be some MYM Chapter 5 related in the future.
