Did you even watch the episode? It was good. Very good. One of my favorites from Season Three. (Also, for anyone saying Alicorn Twilight is ruining the show because it's "not what the creators would've wanted", Lauren Faust herself said she wanted Twilight to eventually become Celestia's successor. Becoming an Alicorn and a princess is bringing her two steps closer to that, so I say again, fuck off.)
You did nothing wrong, Twilight, my love. You are not guilty of anthing, you don't deserve to suffer. Forget the detractors and just be yourself, Twily. Remember that you'll always have those loyal to you. You'll always have me. The same goes for you, Derpy. You're a good mare and a good friend. Don't worry, we love you. And I thank you for helping Twilight. I'll do my best to help you both.
Twilight was born as an unicorn, she should die as an unicron, not as an alicorn! If they wanted her to be an alicorn, they should have done it since the first episode! But maybe at the end of the episode she will turn back into a simple unicorn... Who knows?
I just don't like the idea... :/ It's just like if Rainbow Dash suddenly becomes an Unicorn... It doesn't make any sense. (Discord : "What fun is there, in making sense?") Or maybe she will realize that friends really are "magic", and not stupid wings! Well, I hope so.
