And so Spike narrates Celestia's letter.

"My dearest most faithful student Twilight. You know that I value your diligence and that I trust you completely. But you must simply stop reading those dusty old books!" Twilight's control of her magic is lost thanks to her shock and despair from hearing that letter. She become, Nightmare Moon. At that moment, Moon Dancer also become Nightmare Moon.

What a surprise in living sarcasm because this sort of thing happens to lonely book studying people, not just ponies. Guess who came early for this "party", you guessed it! Nightmare Moon! These recent failures drove Celestia to become Daybreaker because how dare they become Nightmare Moon!

Now the three inviters must put an end to this nightmare madness. Or do they?

Four light rainbow beams of harmony, from each of the four wherever places far far away, decend upon the four nightmares and gives the four remaining familiar people a break, simply because 4 is out of style.

Two nightmares, MidNightmare Moon and Nightmare Moon Dancer, become Twilight Sparkle and Moon Dancer. Two nightmares disappeared to somewhere else. Spike waited too long to have his Twilight back "Twilight!" as he gives her a hug.

But it was too late. Twilight did not hesitate to apologize for not coming to her party and not doing any of the things she was supposed to do for Moon Dancer. Twi only asked her to not let Twi's mistakes be why Moon Dancer does not make friends.

The three inviters and the bookkeepers are cued.

Finally, Moon Dancer is better and forgives them.

Although the Twilight he sees in front of him is not quite the Twilight he knew, the changes to her was long overdue for he requested them long ago minus the whole nightmare part. Regardless, Spike tried again.

This time, he succeeded.

"I'm so glad you're back Twilight!"

It is then Twi and Spike realized they need an adventure.
