Story:

Harmony was on the ground.
Royal Dash went up the stairs to her.

Royal Dash: Harmony ....?

Harmony: How could you beat me again ... you're just a little thing !!

Royal Dash: Maybe for you ... but not for the other ponies ...
When I was a foal I met you before .. you said I would never become a princess but you
look like what I stand here today ...

Harmony: You always said friendship was so important!
I have enough friends!
I have many friends and their friendship should be enough to defeat you !!

Royal Dash: I do not think that just friendship that's what you need ...

Harmony: I will destroy you anyway!

Harmony started collecting a lot of magic.

Harmony: You'll see what you got from it!

Magical Star: Royal Dash! We will get help !!

They ran out.

Harmony: Your friends have left now!

Royal Dash: omg ..

Royal Dash sat on the floor, hoping everything would turn out well, and suddenly
the door opened.

Celestia: Harmony!

Harmony: ? ... Mum ?! What are you doing here?

Celestia: Stop you!

Harmony: ..... I think you did it ....

Royal Dash: Huh?

Harmony: Royal Dash ..... I'm ... I'm so sorry !!

Harmony started crying.

Harmony: I can not help it ... I thought I would never get an important role as a
princess otherwise!
And since you knew what I wanted ... I thought ... I have to destroy you so that
nothing gets in my way ... that you are so strong I did not know ...
can you forgive me?

Royal Dash: So you've done so much to me .... but I forgive you!

Harmony: Thanks!

Royal Dash: But you should have known as Celestia's daughter that you become heir
to the throne ..

Harmony: But I was not sure!

Celestia: But why did not you talk to me then?

Harmony: I did not want you to think I was stupid!

Celestia: I would never do that!
You can talk to me about everything!

Harmony: I'm so sorry what I did!

Royal Dash: But it's okay! You've apologized and it's okay ..

Harmony: Thanks ....
