Can you keep a secret?

Twilight Slade

Discord arrived just outside of Maretropolis, some kind of forcefield was keeping him from actually entering the city.
"Well that's just rude! What is this disgusting wall of shadows anyway?!" He asked. No pony answered.
"Fine, I'll find another place to crash. Wait what's this?" Discord noticed the dimly lit lanterns of the sisters home.
"Interesting."
The ruler of chaos entered the home, he noticed the door to the basement.
"I can't resist! Maybe they have gems!" Discord broke the lock and entered to find Twilight and the others.
"Discord! For once we're glad to see you." Rainbow Dash says.
"Quick do you have a mirror?" Twilight asked.
"Of coarse I do, I always have one when I'm lonely, ooh Fluttershy there you are!" He say hugging the insanity pony. She growled at him.
"I'm not Fluttershy! My name is Butchershy!, get it right!" She shouted.
"But. . . What in Equestria happened to you?" He asked heart broken.
"She's been turned to her insane self. We need a mirror stat!" Twilight tells him. Discord poofed a giant mirror and the insane three saw their reflections.
Twilight cast a spell on the mirror so that they'd revert to their original selves.
"No!" They all screamed, they were transformed normal again. They looked around In confusion.
"What in the world happened?!" Rarity asks.
"I don't know, but why is my hair flat?" Pinkie adds fixing her hair making it its puffy fluff again.
"Oh dear, why am I holding this knife?!" Fluttershy asks bumping into Discord.
"You're all ok now that's all that matters!" Twilight tells them.
"What about Sombra and the sisters?" Rainbow reminds them.
"We gotta stop em' before they cause anymore trouble." Applejack inquired.
"Oh, is that why there is a shadowy forcefield blocking the city?" Discord asks.
"Maybe. They must be keeping the other ponies captive." Twilight says trying to think.

Luna had just sent the message to Cadance and Shinning Armor, they couldn't believe it. Flash was possessed by Sombra and was headed toward Ponyville. Cadance and Shinimg couldn't just leave their citizens unprotected.
"You go see Celestia and Luna, I'll stay and keep the royal guard up." Shining tells her.
"Ok do be careful, Shining." Cadance said hugging him. She took off for Canterlot to meet up with the other princesses.
"Cadance thank goodness you came." Luna says welcoming her.
"I herd what's happening, Shining is watching the Crystal Empire. What do we do?" she asked.
"If I know for sure, he might want his throne back. Maybe worse a more powerful one." Celestia says with worry.
"We all know Twilight is the strongest of the four of us." Luna says sadly.
"She's already with him isn't she? We need to get her and her friends away from him." Cadance says urgent to get her sister out of danger.
"Actually, they are safe for now. The sisters have them away while Sombra takes Maretropolis." Celestia tell her niece, " I just hope she knows what she's doing. "

Sombra began to head back to his daughters house. The citizens of Maretropolis were now in his power. He was shocked to see them waiting just outside the forcefield.
"What on earth- how did you get out?"
"That would be me, Flash." Discord says, "or is it Sombra now?"
"My name is Sombra, Flash is gone!"
"Flash is still in there. I know he is!" Twilight says sternly.
"Keep dreaming princess. Might I say, you are very smart getting out."
"I'm the princess of friendship, I have my friends. Friendship will always win, Sombra."
"Oh will it now? It sure didn't save this one now did it?" Sombra asks letting a portion of Flash speak.
"Twilight?!"
"Flash. . ."
"Hue hue hue" Sombra laughed at her saddened expression. He used his magic and a black crystal began to form in front of her.
"Twilight!!" Her friends called to her, they seemed so far away to her now.
"My friends. What did you do to them?!"
"Nothing dear, they just don't want to ruin your time with Flash. You do love him after all." Sombra says as an image of Flash appeared before her. What Twilight didn't know was she was trapped in her mind by the crystal like last time.
"I-I do. I do love you Flash." She admitted. The image reached out to her, she reached out as well.
"Don't touch the crystal!!" Discord yelled to her. She snapped out of the trap, only a few inches too late. The crystal gave off a dark aura as it surrounded her.
Scarlet and Ellei came from behind Sombra and watched the transformation. The darkness dissolved and Twilight was freed. Her wings and horn had red sharp edges. Her eyes also red. She looked at her friends sadly, tears streaming down her face.
"You could have saved me. . ."
