Spike was snoring atop a stack of books. It was late and twilight had left a few hours ago. Spike, being her trusty companion, tried to tidy up the library. He couldn't stay awake any longer and had decided to take a nap, which soon turned into a two hour snooze. He woke up with a start when twilight came through the door. The sound caused him to jolt and tumble offs the books. She saw him and laughed "Sleeping on the job I see?"
He shrugged and laughed at himself. "Yeah, sorry. I tried to clean up some."
She just looked at him. "Of course you did.”
Spike sensed something he didn't like. He couldn't tell what it was. 'Is it just me, or is the air suddenly really cold?' Also, something about twilight's tone was different. He'd never heard her talk like that. He was so lost in thought that he didn't realize that twilight had been staring at him the whole time, with a small, little smile.
"Um twilight, are you okay?" He asked.
She nodded "Oh, I'm just fine."
He could feel himself growing uneasy. “Okay... well I'm going to bed now," He began to walk away
Twilight tilted her head "Spike?"
He turned around hesitantly and saw that her pupils were really tiny and she gave him a wide toothy grin. He gasped in shock, but when he blinked, she had a look of concern on her face.
"You okay? You seemed on edge," She said
He shrugged "just kind of hungry I guess..."
She gave a nod of understanding, and reached into her pack "Here, have some of these.” She handed him a bag of cookies
Spike took them and began eating them.
"Who made them?" He asked. silence...
As he turned around he discovered Twilight was gone. "Twilight where are..." he gets hit by something solid.

Spike woke up with hazy vision, he saw a purple blur.
He heard twilight's voice "shh, its okay Spike, it’s alright, just take it easy"
He then saw it was Twilight "what happened?"
She giggled not so comfortingly "you knocked yourself out with the club in my hooves"
He looked at her strangely "What?"
Spike felt parts of his body were cold and suddenly realized he was bound to a table with thick metal braces, they reminded him of cheesy old horror movies, where somepony would be bound to a table and have things connected to them and was looking up, towards the ceiling looking up “what’s going on?" he said now feeling the fear rise inside him
Twilight examined a large thin needle as she squirted it a little to get the right amount of a green fluid
"Oh, nothing I'm just going to do some, tests on your body"
He struggled against the metal braces "why am i bound to the table?"
She tapped the needle "because you’re going to feel a lot of pain"
Spike gulped "why are you doing this?"
She then turned to him and looked him level in the eye "because i need to see how much pain a dragon can endure"
What shocked spike the most was that she said it with such a nonchalant attitude
It was as if this was an everyday conversation with his best friend, he winced as she put the needle in his arm and pumped the liquid into him.
"What’s that stuff?" he asked worried
She placed the needle on the table, and began searching through some chemicals
Then stated "just adrenaline, don't want you to fall asleep in the middle of such important research"
Spike then gasped as the adrenaline took over, he felt as if his heart was going twenty beats a second, he panted hard, trying to control his ever increasing heart rate.

Twilight turned around with a beaker of liquid, she used a dropper and soaked some up. Then she dripped some on his arm, it fizzed a little, and spike raised an eyebrow.
She put a hove on her chin "hmm" then she said "i got it!" she turned around
Spike was wide awake and felt like a swarm of flies was buzzing around his head.
She turned around with a small knife and he gasped "no, don't!"
The knife touched the scales of his right arm; he could feel the cool metal even through his thick scales.
She smiled as she slowly began scraping against the grain of his scales; a row of them caught and were turned upwards, vertically
Spike winced as she then sliced sideways and began to tear up.
She then put the knife back and then her horn glowed with magic suddenly and viciously the patch of scales was ripped off.
Spike yelped "stoop please" she dabbed the blood that had pooled, then she turned back around to fill the dropper, she then dripped five small drops onto his bare skin
Spikes eyes went wide as the acid began to fizz and bubble violently as a small stream of smoke went upward.
Twilight shook her head "oh spike your a drama king, now i know why you like rarity!"
The acid had eaten halfway through now and his arm looked like Swiss cheese, holes riveted through it, as blood trickled from the grizzly wound.

Twilight looked at spike; he was exhausted from screaming and couldn't take the pain much longer.
"Hmm" she said puzzled "where else is there soft tissue?”.
She then looked at spikes watery eyes "aw dry those tears up, or better yet let me help you"
Spike squirmed "NO, BUCK YOU!"
She then dripped some on his closed left eyelid it violently reacted with his tears causing it to burst into green flame
It burned its way through the eyelid and his eye began to boil into jelly. Spike wailed in sheer agony, he had never experienced pain like this before. As he tipped his head to the side, the liquefied remains of his eye dripped out onto the table. He looked horrible. The skin around his left eye was gone, exposing the bone, and his empty socket. His other eye was constantly streaming with tears. “Why are you doing this?" he asked with clenched teeth
Without even blinking Twilight said "because your assisting me in finding out a dragons weaknesses”.
She then gave him the same smile that had flashed earlier
And just like that, he blacked out.
