This is how Twilight's Summer Sun Celebration goes in Princess Twilight Sparkle Part 2.
[Later a huge crowd is gathered]
[Twilight stands ready]
Princess Celestia: Citizens of Equestria. This Summer Sun Celebration not only celebrates the defeat of Nightmare Moon but the return of my sister, Princess Luna.
[She raises the sun and Luna lowers the moon as Twilight performs a Twilight boom on the stage]
Stormer: I knew she would get a hang of the flying sooner or later.
Breez: Way to go, Twilight!
Nex: That's my little pony!
Rocka: Good job, Princess!
Stormer: Everything seems fine. However, there's one file from Canterlot that's missing and it seems Black Phantom sent it to an unknown destination.
Princess Celestia: Which file?
Stormer: The file that contains the location of the Tree of Harmony.
Princess Luna: And whoever Black Phantom sent it to, now knows the location of the Tree of Harmony.
[[They look at each in concern]
[Meanwhile, an Unnamed Villain gets the file]
Unnamed Villain: [laughs evilly] Finally, the location of the Tree of Harmony. Soon I will destroy it using my beautiful little brains. [laughs evilly]
