"So...you say that I should help this relationship culminate?"

Celestia read over the letter once more, happiness bursting in her chest.

"I will gladly do so, Ditzy Doo, but...why, exactly, do you condone this?"

The grey Pegasus raised an eyebrow, looking Celestia right in the eye.

"Princess Celestia, have you forgotten about the Elements of Harmony?"

It was Celestia's turn to raise an eyebrow.

"No. Magic, Kindness, Laughter, Generosity, Honesty, and Loyalty. Why would I have forgotten about them?"

Ditzy Doo sighed, looking down to the ground.

"Yes, Celestia, you have."

Celestia sighed, looking at Ditzy Doo with an air of impatience. After a few moments, she tapped the ground with an ornamental golden hoof shoe.

"Ditzy Doo. I demand you to explain yourself. Why would you say that I have forgotten about the Elements of Harmony?"

The grey Pegasus looked up at her, the Eye of Dreams whizzing through words and history, the Realm of Dreams forever hidden to Celestia's narrow gaze.

"Love. Happiness. Sadness. Determination. Every feeling, every emotion. The thousand-strong Elements of Harmony, that are intrinsic to everypony, and to every emotion. Once somepony has felt them all, they can harness them. One must harness them, in order to truly awaken the One Thousandth Element of Harmony."

Celestia blinked, and chuckled lightly.

"One thousandth, Ditzy Doo?"

"Yes. It is the strongest, and the most elusive. And it begins with the Element of Love, which has now chosen for of your subjects. Yes, four, I know the letter says two, but it is four. However, two of them are deep-set, familiar Elements of Love. However, two of them...are spontaneous, beautiful, true Elements of Love. One of them will become the One Thousandth Element, Princess Celestia. And, to do so, they must fully experience the Element of Love: the Nine Hundred and Ninety Ninth Element of Harmony. When they do so, they will experience every single emotion that there is to experience. And then, all of those emotions, and the Element of Love, will culminate into the One Thousandth Element of Harmony."

Celestia blinked, flustered.

"Well...I believe that certain arrangements must be made, then."

She jotted down something on a form, which she impaled on her horn and made an OCD (Official Canterlot Document.)

"There..."

Ditzy Doo raised an eyebrow, curious as to the changes made.

"What did you do, Princess?"

"I shortened their time on the train from fourteen days, to seven, and the time in Manehatten from seven, to fourteen...if we truly need the Seventh-excuse me, One Thousandth-Element of Harmony to fight Discord, then I want them to experience the Element of Love in Manehattan, not on a train."

She bolted upright, a sudden thought coming to her as she made a second OCD.

"What was that?"

Celestia smiled, and explained what she had just done. Ditzy Doo smiled as well.

"I believe that the Element of Love will flourish, Celestia...and besides, they would have to ride a train there to board the cruise, anyway, correct?"

Celestia nodded, wishing her subjects the best, but sighed, a question weighing heavy on her mind.

"Ditzy Doo, why don't I remember the one thousand Elements of Harmony, and only the Seven?"

"Because...Drøm Mester and I took the memories from you..."
