Can you keep a secret?

Sombra

Twilight, Rainbow and Applejack fought their now insane friends. Ellei and Scarlet fled with the bottles and Flash. The creepypasta ponies all vanished through the darkness that was behind the staircase. The ponies managed to escape their changed friends and went after the sisters. They were in an opening where the moon shines down on some sort of sacred ritual grounds. Flash sat in a throne like chair in the center of the altar, he was wearing Sombras crown. They slowly approached the altar, their altered friends close behind. Pinkamena, Butchershy and LMR ran around the tall stones that surrounded the altar. Twilight and her two sane friends gasped at the sight.
"I'm tired of this princess getting in our way!" A voice said from behind one of the stones.
"I agree! Sombra should have been back hours ago!" Another voice said.
"Now girls, the time isn't just right yet." Scarlet says coming from behind the throne. She caressed Flash' cheek letting out a small hiss, revealing her snakelike tongue.
"Let him and the others go!" Twilight ordered.
"Ya! Or you'll be sorry!" Rainbow added.
"I highly doubt it." Ellei says coming up next to Scarlet. Her black with red pupil eyes began to show a black stream of ooze.
"Let the ceremony commence!" Scarlet declared. The four ponies from before and another appeared from behind the tall stone pillars. This last was white with black striped overalls on, his muzzle had stiles on it as well.
"Best get comfortable to watch the show!" Pinkamena says and the three deformed friends held back the remaining three.

The five creepypasta put the bottles in their places in front of the pillars. Twilight and her friends struggled, the three seemed stronger now. Ellei signaled when the moon was at its highest peak, the bottles were spilled. Fives different life forces leaked toward the throne.
"I call forth the king of darkness, consumer of love, the dark-hearted master of night. King Sombra, take this colts form and reborn yourself!!" Scarlet says in a booming voice. A purple-green aura engulfed the throne. Flash' eyes shot open. His fur became a dark grey, his mane black. His eyes were now red with slits. The creepypasta ponies each stepped away from the altar and into the woods, Ellei waved at Crimson as they left, he waved back.

Flash stepped off the throne a new colt. He was greeted by Scarlet, who's eyes were normal again.
"Welcome back father." She said
"'Father?!'" The three repeated in shock.
"Thank you for bringing me back my child. I'm so proud." He said hugging her. He looked up from her to twilight, he grinned at her, revealing fangs.
"Who is this?"
"Oh, father this is Princess Twilight Sparkle, Princess of friendship. And her portion of friends." Scarlet introduced them as their insane friends joined Ellei's side.
"Capturing a princess for me, so kind of you. Who's YOUR friend?"
"This is Ellei! Ellei Beats! She's a creepypasta pony. I found her in an abandoned lab. We became good friend after a while, she's my sister now." Scarlet says hugging Ellei.
"I'm happy for you. Now let's see about the rest of Equestria" he says eyeing Twilight with an eager, seductive look.

This was not going to be quite the fun. . .
