When she returned, they noticed that she was wearing a clean, white apron. And she was carrying a metal box with her. "Is that a white apron... worn by... surgeons?" Asked Rarity. Rainbow felt uneasy again.

Pinkie Pie corrected Rarity. "Don't be a silly big filly! That's a baker's apron. She want's to bake a cake like I would, to better understand my mind." The ponies were almost convinced at what Pinkie Pie said, until they saw Twilight put on a surgical mask, open the box, reach inside, and take out what looked like a surgical knife. Everyone's eyes grew wide with concern, with the exception of Pinkie Pie. Pinkie was so excited. "I knew it! And that's the knife to cut the cake! Right?"

"Something like that." Twilight chuckled. Twilight held the scalpel close up to Pinkie's face. "Here's for science."

"Heh heh. Careful with that knife." Pinkie said nervously.

Dash's heart beat significantly faster at the sight of a knife that close to her friend. "Twilight. I don't want to do this! Please let me go." Yelled Dash.

Twilight was vexed. "Why not? Your silly nightmare?"

Dash replied, "This is getting more and more like that nightmare. What exactly do you plan on doing with that knife anyway?"

Applejack joined in. "You're worrying us Twi."

Twilight sighed in frustration. "It's for science. We just went over this. I thought you were okay with this."

Pinkie watched as the knife hovered down her chest and to her belly. "Shouldn't you be baking that cake now?"

The knife caressed the skin of Pinkie's belly. Suddenly, Twilight pushed harder on the knife, and the extremely sharp tool cut through the skin and muscle of the pink pony's belly. "OUCH!" Pinkie yelled. Then Twilight quickly moved the blade straight down the belly, making a deep horizontal gash through the skin and muscle, causing Pinkie to scream in pain. It was not long before red liquid was seeping out of the wound.

There was a sudden adrenaline rush in everyone, from seeing what just happened

There was a sudden adrenaline rush in everyone, from seeing what just happened. "TWILIGHT!" Both Rarity and AJ hollered.

Rainbow Dash was now filled with panic. "GET ME OUTTA HERE!" Dash screamed, while jerking franticly, trying to break free from the metal cuffs, but to no avail.

"Don't worry Dash. I will." Rarity said, with a look of anger and determination towards Twilight. Rarity's horn glowed as she used her magic to take hold of the knife, right before Twilight was going to make another incision into Pinkie. Twilight had an annoyed look on her face. And the irises in her eyes... turned red.

She tried to regain control of the scalpel with her magic. "Rarity! Stop it!" They were both fighting for the knife, pulling on it like a game of tug and war. The purple pony had had enough. She used her magic to flip a switch on the control board at the center of the room. This sent a powerful electric shock throughout Rarity's body. Her muscles instantly contracted. She shook and jerked violently, screaming out in agony from burning heat. This left her twitching and disoriented, allowing Twilight to take control of the surgical tool once again. All the pony test subjects had never been so scared in their lives.

Turning off the power, and returning to a crying Pinkie, Twilight used her blade to make two more deep gashes on the chest of her pink friend. Both cuts were slanting down, their bottom ends joining together, along with the top end of the first cut on Pinkie's belly. There was now a capital Y shaped incision on Pinkie's entire underside. The Y turned red. The blood was beginning to flow down Pinkie's chest and tummy, down to her legs and dripping onto the floor. Moaning and weeping she innocently asked, "Twilight... why?"

"*Snort* I get it. A 'why' incision. That's really funny Pink. Cliché, but still funny." Snickered the surgeon.

Rarity recovered enough composer to once more take control of the knife. Twilight was getting angry. She again turned the same electricity inducing switch on. "Rarity! Quit it! You're being immature!"

Rarity was in intense pain as before. The electricity was roasting her body tissue to the point where it was smoking. But she fought against the horrible burn, more determined than ever to stop Twilight. Rarity used her magic to move the knife away from Twilight. Everyone else was watching in high hopes. The book worm unicorn's anger grew. She turned off the electric current and had a quick sip from her glassware in frustration. The next thing Rarity knew, Twilight seemed to easily yank the sharp cutting instrument with her raging magic. "That is IT!" Twilight brought out a bone cutting hacksaw from the silver case. Rarity tried to move the saw away from her with her glowing horn, but Twilight's magic was now too overpowering, as if getting her mad was making her magic stronger. Coming to Rarity with the hacksaw, she positioned the teethed blade at the base of the white unicorn's horn and started sawing.

Rarity's magic was getting weaker with each thrust of the saw through her horn. She winced as the blade cut through some skin at around the base of the horn. A small amount of blood flew down her face. After about 30 seconds, Rarity saw her blood-stained horn drop to the ground. Everyone's heart sank as they watched what seemed to be their last hope of escape fall to the ground and die. Twilight let out a warning, "Anypony else who resists will be dealt with by my magic. Now, if that's all."
