My Little Pony: The Adventure of Friendship. Episode 1: The return of Discord.

In the Labyrinth of Discorded memories.

"Doctor!!" The grey furred mare called, desperation in her voice and expression. "Oh, Doctor, where are you?!" She soon found herself getting overly worried as she ran some more when she heard a faint voice call.

"Ditzy?"

"Oh, Doctor! There you are!" She exclaimed, running into an opening in the never-ending labyrinth.

"Why are you here, Ditzy?" He had a sound of remorse in his voice as he tampered with his Sonic Screwdriver.

"What's wrong, Doctor?" She asked as a familiar purple mare walked up beside the doctor.

"Oh, hello, Derpy." Twilight Sparkle said with a sarcastic eye roll. "Doctor, why is she here?" She glared in the gray mare's direction.

"Right, I almost forgot!" The brown stallion started to read over a paper. "Ditzy, You're no longer my companion."

The mare could feel her heart stop. "W-what?" She stuttered, seeming to be at a loss of words. "I can't believe he replaced me...." She thought, staring at the blue eyed male.

"I'm very sorry, Ditzy." He continued, then stopped. "No, wait. I'm not sorry! You were a very lousy companion in my opinion." He said as he snickered softly.

Derpy lowered her head and kicked at the ground with her hoof. "Fine... I-I don't need you anyways... Who would need their best friend, when you've got the others who will treat you better?..." Her coat turned a more of a deep gray as she walked out of the area.

"It worked!" A voice said, getting overly excited about the turn-out.

------------------------

"Ditzy!!" The stallion's voice echoed through the never-ending Labyrinth. "Ms. Hooves?" He searched around, the gray mare nowhere in sight. Soon, the brown stallion grew worried. He ran and ran for what seemed like forever, until he found an opening. "She has got to be in there!" He thought, while he casually galloped in. That was then when he heard a familiar giggle, sighing in relief.

"Oh, Ditzy, there you are!" He said, relief honeying over his voice. "Oh, how I was so worried about you, Ditzy..." He then stopped in his tracks, his ears folding back as he stared at the mare. "Ditzy?..."

"Oh, hello, Doctor." She turned to face the other, a blue Pegasus at her side. 

"D-Ditzy?...." He stuttered as he began to tremble slightly.

"Something wrong, Doctor?" She asked while smirking.

He lowered his head, shaking it repeatedly. "No.. Nothing at all..."

"Oh! And one more thing, Doctor?"

"Yes, Ditzy?" He asked, hope filling his voice.

"I'll no longer be your assistant."

The stallion's heart shattered, his coat turning gray. "F-fine..." He brought his head up to look at her, his ears still folded back. "I-I don't need you anyways!!" He turned around.

"Good thing, huh?" She asked, sarcasm dripping like venom in her voice.

"Yeah.... Good thing...." He muttered as he trudged out of the area.

"It worked on them both, splendidly!" The voice giggled in excitement as the two trudged out of the labyrinth.

What's in store for our heroes!!! Will this be the end of Doctor Whooves' and Derpy's friendship? Or will their friends find a way to save them before it's to late? See what happens next chapter!
