finale spoilers!!!!!!!!!!
SO LIKE .. cozy glow .. the little girl who was twilight’s assistant at school turned out to be the big evil for the season and once they figured it all out at the end of the two-parter they literally just. put her in a cage. and sent her to TARTARUS (basically purgatory for ponies and magical creatures ??). right next to tirek. thats just where she is now. CELESTIA did that. twilight had one small line about like “friendship is power but we dont make friends for power, im sorry that i couldn’t teach you that” before she was taken away but theres no discussion with her after that …….
