something

Deep in the darkness of the Canterlot dungeon lit only by torches down a long hallway, Celestia walks slowly to the room where her former student is locked away. The dungeon is very dark, quiet, and had a very musty smell to it. Celestia finally reaches the end of hallway to a giant steel door, indestructible to anything other than Celestia's own magic. Celestia sticks her horn into the small hole on the door to unlock it, then walks inside slowly. Then a light comes on.

"Hehehe... Hello there Princess Celestia" said a psychotic looking Twilight Sparkle. "It sure has been awhile since you visited me down here"

"You know why I'm here Twilight, I'm here to finally kill you, you have been trapped down here far too long, and i just can't have you alive anymore, your element of harmony is useless and must be passed on to somepony else."

"Hehe, oh Princess, you always did make me laugh, you cannot kill me, I'm immortal now, remember, and after all these years, you couldn't possibly kill me, i'm your favorite student."

"I can too kill you Twilight, I have the magic and the strength to do so."

Twilight tries with all her might to break free again, but the magic chains around her prevented her from doing so.

"I never should have granted you the ability to be a princess, it just made you go mad" a tear falls from Celestia's face onto the concrete floor she stands on. "I just wish I could have the old Twilight back, but once a pony becomes an alicorn, it's irreversible."

"Oh shut up Celestia, you made me this way in the first place, that must mean you love me this way... unless you trapped me here on purpose because you're afraid I'll replace you as ruler of Equestria."

"Twilight... I did love you, but your actions have killed thousands of ponies, and I cannot allow those actions to continue."

"Fine... go ahead, kill me, you don't have the heart to!"

She was right, Celestia didn't have the heart to kill her very favorite student.

"...You have one more day Twilight Sparkle, ONE MORE DAY!!" Celestia exits the rather large cell and locks it again, then starts walking back through the very long hallway and out of the dungeon.
