“What is the last thing you remember?” Twilight asked.
“Talking to you.” Dash responded.
“Before that?”
“....Waking up with you hu—“
“B-b- before that to.” Twilight said waving her hands in front of her while she finally buttoned up her lab coat.
“Umm” Dash thought scratching her head. “I was... flying... and I... hit my head. Hard.”
“Can you say the alphabet for me?”
“A, B, C, D, E, F............ f?...............f? Ummmmm..........................f?”
“Stop, stop, that’s good enough.”
Twilight paced from side to side. Rainbow Dash watching as her lab coat blew in the wind. She mumbled magic equations to herself that Rainbow didn't understand. Finally she stopped and looked at Dash.
"My theory is when you... got hurt…. not all of you... healed properly." Twilight finally said. Dash scratched her back, still hoping Twilight would find a way to put her wings back on one day. Twilight looked sad for some reason.
“I’m going to have to teach you all the information you have forgotten.”
Just then a button burst off Rainbow Dash’s tight green blouse hitting the wall behind Twilight. The unicorn just sighed levitating the button and a thread forward to Dash’s exposed chest. The rainbow maned mare just looked down as she stitched it on, like a school filly having their parent tie their shoe. There was also the problem with her body.
~~~
Before she started her lesson Twilight took the time to examine Dash’s body. Giving her a health check up. She had rebuilt her from so many different ponies even she lost track after a certain point. It was important that all the parts were working together properly.
Her flesh was the same healthy cyan coat it always was with the addition of amateur stitching, but her skin was also a lot colder.
Despite being animate her body was only room temperature. This was very troubling for Twilight since as far as she could tell blood was pumping through her body. It was not like what she did was necromancy, she used science, or rather as much science as she could on the subject. It may have technically been necromancy, but she didn’t use any necromantic spells to do what she did. Rainbow Dash’s now considerable chest made it hard to get a heart beat, but it was pumping blood, and she was breathing. Her organs also all seamed to be working. Her body should be warm, but it was not. This fact did not seam to bother Dash in the slightest, who had no problem wearing her skimpy outfit Or even nothing at all when Twilight asked she wasn’t even shivering. Twilight wondered if her ability to judge temperature had been damaged.
Physically Twilight tried her best to replace the mare’s muscles to the level she had in life. Aside from the enhanced mammary glands. Which she still did not recall adding.
Twilight tested her with: jumping jacks, push ups, running on a treadmill, crunches, and squats both clothed and unclothed taking extensive notes of her form. Whatever Twilight put her through the mare did not sweat a drop. She even raised the temperature in her lab as high as it would go and told her to run every single test again but this only got Twilight sweaty making her unbutton her lab coat yet again. She added to her notes that Rainbow’s endurance was seemingly limitless as well. Despite doing exorcises designed to test or in some instances break endurance, Dash pulled them off with flying colors never resting for a second. The mare was a machine. A machine constructed from the bodies of countless individuals with the partially damaged mind of one of her best friends.
Twilight watched Dash work out in front of her, taking carful notes of her form. The movement of her muscles. The tugging on the stitches as they tightened and loosened with every flex. Her thin legs and thick thighs smacking into one another after the splits. Her massive tight ass poking up just over the edge of her shorts as she bent down. Not to mention the jiggling of her boobs as they flopped up and down without a bra with each jump, the stitching on her shoulders and chest trying just as hard as the ones in her ill fitting raggedy shirt not to tear. The stitching covered every inch of her body in strange patterns that also made sense when you thought about them. Every part of the former flier was rapped in them, and Twilight took note of each and every one making sure none would rip.
“I think we are done for now.” Twilight said standing up from her chair and popping her back into place.
Dash finished her 3,671st push-up and stood.
“I’m going to bed, you tired?” Twilight asked before yawning.
Dash shook her head.
“Well try to get some sleep anyway.”
Twilight went up the stairs of her lab leaving Rainbow Dash alone. The former cadaver shrugged lying on her back in the very bed she was resurrected on as Twilight extinguished all light sources.
Up stairs it was morning, but it still rained outside. Regardless of what time it was outside Twilight was exhausted. She used magic to close all the curtains in her house, placed the clip board on her night stand, stripped down to nothing and collapsed on her bed collecting her thoughts as she drifted into the land of dreams and emotions.
In her slumber she dreamed of the face of the stallion who’s parts she stole. Not only him but all the others. Their forms were twisted and stitched. Stolen from their graves and used to make a beast like spider of spare parts. Intestines for legs, hands and hooves sewn to the ends a bloated fly body with multiple heads each moaning, and asking the same thing. “Why?” The thing getting closer and closer to the foot of Twilight’s bed. Twilight was paralyzed. It stood over her, dripping its stinking decay onto her. It’s shoulders split down the middle releasing a stench so foul she could taist it. From the center of the pink mouth surrounded by the heads of Twilight’s own victims was a single head. One with a rainbow mane and cyan flesh.
