Day of the sammer solstice(quarrel sisters)past 20

The elements are worked out, and Comet has magical wings like those of Cosmos, only pink. Kosmika has become herself again. The comet approached her.
Kosmiko, how are you? All is well?
What happened to me?
You could not control all your anger and became angry.
What?..
Kosmiko, forgive me... All this happened because of me. If I had given the title of princess to you, all this would not have happened...
Princess Twilight, Flurry Heart and Luster Dawn flew here.
Girls! Are you all right?! Twilight asked.
So...
Mom.
Yes, Comet?
I don't want to be a princess anymore.
What?! But why?!
I turned out to be a bad princess. I could not find a common language with my sister, and therefore she took offense at me and almost destroyed Equestria. When I checked the preparations for the holiday, all the ponies expected to see Kosmika as a princess, not me. I couldn't even solve these problems. I am a terrible princess ...
All present were silent.
I'm sorry, dear, I don't want to offend you. - said Beautiful Night.
Really, we just thought that the eldest daughter should become a princess. - said Apple Bun.
You are not to blame for this. I couldn't even beat Kosmika in any way.
And how do you think she became like before? Twilight asked.
Magic?...
So . Look at your head.
Comet looked and saw a silver crown with a pink star.
So I am also one of the elements of harmony?
So .
I'm sorry, my sister. - apologized Kosmika.
It's OK . I'm not angry. But promise me, please, if something happens next time, tell me right away, I'll help you.
Of course.
Sisters hug. Comet's wings disappeared and they all went home together.
End.
But not the end of the whole story.
This is just the beginning.
