"Noooo!" Twilight screamed as she heard the sound of a saw buzz to life.

'There's got to be some way to make her believe? But how? Oh, no! Wait... maybe...' She thought to herself.

"Celestia! I'll talk! I'll talk!" She screamed even higher.

The form of her mentor came into view, still with a scowl.

"Well?" She asked harshly.

"I'll tell you what you want..." She sobbed. "But first, look through my memories."

"Why would I need to do that? It's not relevant to where my student went!" She snapped. "Do not play games with me you roach."

"Please... just do it. I want you to look through them all. Every last one." She looked up at the alicorn with tear stained eyes. "As a last wish before this." She nodded tot he large saw looming over her heart.

Celestia silently mulled it over before giving a snort. She lowered her horn and touched Twilight's head. Twilight immediately froze in shock as she felt the elder's magic go through her mind.

Inside Celestia nearly choked on her breath.

Twilight's memories.

"Thank you Twilight." Celestia said as she watched the small filly finish organizing the scrolls. "But I did not need them organized as of yet." She smiled.

The smaller Twilight gave a small giggle and blush before jumping down to nuzzle her mentor.

"It’s what I do best!" Chirped the small filly.

"What you do best is bring me happiness." Celestia said laughing.

The memory faded and was replaced with another.

"What would Rainbow Dash do!?" Twilight quickly asked herself as she looked at the hydra.

A thought came to her mind before boldly running ahead, yelling “charge!”

It snapped at her, but instead flipped itself over and got six mouthfuls of dirt.

The memory faded and Celestia immediately recognized from earlier events.

Earlier events

The changeling was sitting in an upright position.

“… New queen.” Twilight’s eyes went wide as the changeling plopped down onto it’s haunches, lifting it’s upper body as much as it could. It’s hind legs spread, revealing an aperture near the crotch of the beast’s carapace, and even as she watched, it spread open. Green fluid leaked out onto the stone floor, preceding a shaft of pink, knobbed flesh. Twilight gasped at the sight as it emerged into the cool air of the modified cell, twitching and oozing more lime-green fluid from the tip. “New queen.” The changeling repeated, it’s eyes fixed on her.

“What?” Twilight whimpered, looking up into the changeling’s eyes.

“New. Queen.” The chains broke. Twilight screamed. Before she could summon her magic, the changeling pounced on her, driving her down to the cold, stone floor.

“Get off!” Twilight grunted, fighting to push the changeling away. Her horn finally glowed, emitting a bright beam of lavender light. The beam lanced off of the changeling, bounding away to hit a crystal, causing it to explode. “What?! Deflected?!” The changeling lowered itself onto her, it’s mouth close to her ear. She heard it whisper softly, even as the knobby, pink shaft of flesh began to rub against her stomach.

“New queen…”

“Get off!”

“New queen.”

Reality

Celestia's magic stopped, the real her shot back, gasping for air as she looked at the sobbing changeling. Her student.

"T-Twilight?" She asked.

She gave a small nod, grinding her fangs as she looked away.

"Doctor Needles," she stated calmly. "Let her down."

The avocado green colt looked at her uncertainly before undoing the restrictions.

"Twilight..." Celestia cried as she hugged her student. "What did it do to you...?"

"I-I can't. It’s just too horrible!" She cried. "D-Do you believe me?" Twilight asked looking up at her.

"Yes. The changelings had not invaded even a portion of land in some of your memories... but the last one I viewed." She gave a shudder before hugging her student tighter.

"Princess! I can't breathe!" Twilight choked.

She loosed her grip before quietly letting go.

"Twilight, when you are ready. You may talk to me. Nopony else. And as of now, I must be at your side at all times." Celestia said draping a wing over her student. "For your own protection."

"Thank you. But, what about my friends? Won't they freak out when they see me? Or what about my brother! He'll try and kill me!"

"Don't worry, he has to obey his princess after all." She started to turn towards the door. "Come, let us go to my chambers. We have much to discuss."

Twilight gave a slow nod before looking back at the doctor and smiling slightly.

As they went, the guards had tried to stop them multiple times before being sent away by Celestia.

Twilight looked around. The halls were a pale white, the floor had an almost see through appearance. Almost like crystals...

"Princess?" Twilight asked as she looked down. "Where are we?"

"Ever since the invasion in Canterlot, we decided to use the caverns as a laboratory. To study science, magic and other things. I'm sorry that you had to see it like this. I was going to give you your own lab, as a birthday present actually."

"Really!? My own lab! That's great! But... I already have a lab." She grinned sheepishly.

"Really? Where?" Celestia asked genuinely interested.

"Under the library." She blushed making her black cheeks lighten slightly.

Celestia merely laughed at her student before approaching a door with a sun seal.

She put her horn into the hole in the middle and gave out a burst of magic. The sound of clogs and gears were present throughout the hallway as the door opened.

Twilight gasped.

"Princess... this is the vault to the Elements of Harmony."

"Yes, and as you can see, the entrance to my secret laboratory. After all, it is the most strictly guarded area in Canterlot castle."

"Besides... him." Twilight scowled.

"Yes… him." Celestia paused recalling the unfortunate events that took place before. "But he is still in the maze. I made sure that is the most highly guarded area in Equestria."

Twilight smiled, knowing that monster was still in stone. But grimaced knowing he was no true monster, that thing was.

"Princess, could we just teleport to you room? I don't want anypony seeing me like this. Atleast not now anyway."

Celestia smiled worryingly before she teleported them both to her room.

Twilight immediately sat down onto her haunches and looked around. She didn't look at anything in particular, nothing until a mirror reflected a small patch of light that caught her eye.

She hesitantly let her magic lift it up. It was hovering over before Celestia put a hoof on her shoulder.

"Twilight, is that really the best thing to do right now? It could cause even more-" Celestia was saying until being cut off.

"Please, I need to actually see myself. I need to..." Twilight gently let the princesses hoof slide off as the mirror started to float over again.

When it did reach her, she sighed.

She was a dark black, four rings of purple encircling her middle barrel, her mane was now thin and slightly pinkish with a stripe of dark red and a shade of purple running down the side, her eyes were slitted but were colored a harsh purple, her horn looked relatively the same except for one or two small holes in it, an the two pinkish wings on her sides. She opened her mouth and quickly put a holed hoof to it, shrinking away from the mirror.

She looked back though, and did it again. Her teeth were whiter than before, they were also elongated and sharpened so much, that anypony who saw her would have thought she borrowed the fake teeth from Luna's last Nightmare Night.

She took in a deep breath before turning to her teacher.

"Princess, I need to send six letters. I need my friends here."

"If you think it would be best." Celestia sighed before levitating six scrolls, an ink pot and a quill over.

She quickly enveloped the letters in her, thankfully, still lavender colored magic.
