Twilight Sparkle was in the recesses of her home making a potion. It would change psychotic pony into a normal tempered pony. But there was a catch unknown by her; the potion would alter if the normal tempered pony drank the potion. She had a psychotic pony in the room with her as a test subject. She learned how to make potions by watching Zecora make them for others.

Pinkie Pie bounced into the room eying Twilight, then asking, "Whatchya doing Twilight?"

"Oh hey Pinkie, I'm working on a new potion that would change a psychotic pony into a normal tempered pony. Psychological is here to help test the potion; he really wants to be change. I think that's what he said. Anyways, in 3 seconds flat, he will change." Twilight answered.

"Oh. Is there a flavor to it?"

"What?"

"You know flavor, the bubblegum taste or cherry. Or, or, or, mm, cupcake?"

"I know what flavor is, I'm a genius! Geez, but no there is no flavor."

"Then he might not drink it."

"Why not?"

"Because it has no flavor, silly."

Twilight didn't pay any attention, she grabbed a small glass and put it up the Psychological's mouth. He drank the potion, but nothing happened.

"What the? When Zecora does potions they always work." Twilight said astonished.

She took a sip of the potion to see if it would work. Nothing happened still.

"Is is a dead end?" Pinkie asked.

"I guess; oh well, I'll try it again. You better go now, I have alot of work to do."

Pinkie bounced out of the room, disappearing into the horizon. The sun was setting as Princess Luna raised the moon.

"It's been a long day; why don't I just go hit the hay and finish in the morning."

But she stopped for a second. She fell to the floor in pain. She was changing.

"What's happening?!"

Once every pony was sound asleep, Twilight galloped into the night, towards Sugarcube Corner. Twilight's eyes were like sombra's eyes, and her mane was all messed up. She slowly tipped toed into Sugarcube Corner. Pinkie was jolted awake by the small tip toeing of a pony inside the building. She got scared, she grabbed the first item she could find in her room. (cupcake) Then she called out to the noise, "Hello? Is any pony here?"

"Ha ha ha." Twilight laughed.

Pinkie entered a hallway and saw a small light. It was green and sinister looking. Then as she looked closer, a figure appeared. It was a shape she had know, but there was something wrong.

"Who are you and what are you doing in Twilight's body?!" Pinkie yelled.

Twilight pulled out a butchers knife and lunged toward Pinkie Pie.

"AH!" Pinkie screamed.

With one hard blow, Pinkie was dead. Celestia raised the sun as Pinkie's life force died. Twilight changed back with not as much pain changing. She looked down and saw blood on the floor.

"Pinkie?"
