All I want are some answers

Pinkie and Marigold sat in the living room as yelling and arguing were heard in the other room. "Mom what are they arguing about?" Pinkie fidgeted on the couch, her one good leg was used to support her.
"Nothing… just about…his job." Marigold bounced up and down on the couch.
"So do you like my cutie mark?" Pinkie tried not to look but eventually gave in and glanced at the three apples, A horrible past that no pony would want to relive was staring at her in the face. Pinkie held back tears and just looked away. "Mom…what's wrong?" Pinkie pie wiped away the tears.
"Nothing honey…this might take a while, why don’t you go play with your friends." Scout slammed open the door.
"No she is not going anywhere." Rainbow walked out of the room with a scowl on her face and tears in her eyes.
"We are still discussing this young colt!" Rainbow yelled violently
"No! I am done trying to convince you about this! It's either this or she goes back to a black painful suffering."
Pinkie jumped to her hooves and held his mouth closed. Scout shoved her hoof away. Pinkie and Rainbow pushed Scout into the other room and slammed the door closed. Marigold listened intensely.
"You are not touching her!" Mary gold believed this was Rainbow Dash
"We agreed…if there were signs then we would put her out. You know that its coming back and intends to take every last one of us with it." Scout tried keeping a calm voice
"I DON'T GIVE A FUCK WHATS GOING TO HAPPEN!! YOU ARE NOT TOUCHING MY LITTLE FILLY!!!" Rainbow was clearly heard yelling through the solid oak door
"We…we need to do this, not just for her but for every pony." Pinkie kept a quiet voice
"Wha…what!? Pinkie what are you saying?"
"We don't have time for this! The mother fucker is listening to us right now! Its it or us!!" Scout yelled violently
Marigold didn't know what was going on but her gut told her to run. The door slammed open but Mary was already in a full sprint. Scout grabbed her hind leg and flung her into the wall. She collided with a large thud and laid on the ground writhing in agony.
"This is for my sister!" Scout was ready to kick her ferociously but rainbow tackled him. Rainbow was struggling with Scout by the door so Mary thought fast, she dove into the kitchen for the open window. Pinkie dove in front of her and blocked her way.
"Marigold just listen, we need to talk this over."
"I don’t understand!" Marigold was shaking violently as tears streamed from her eye's
"Don't worry…we just need you to go to the doctor…everything is going to be fine…scout won' touch you." Pinkie wrapped a hoof around her daughter. Marigold hugged her mother back.
"No!" Scout yelled. Rainbow still had him pinned on the floor.
"It's alright we've gotten this far we can go farther, it's ok-" Pinkie stopped mid sentence. Everypony tuned to see a knife slit into pinkie back, the blade was clenched between Marigolds teeth.
"IT WAS JUST GUNNA BE US AND YOU TURNED ON ME YOU WHORE!!!"
Rainbow ran for her and slammed into Mary. She grabbed the knife out of pinkie. Pinkie hit the ground, convulsing in pain as blood poured from the wound on her back. Marigold looked at what she had done in horror. She thought of her mother and the fact that she might die, but her thoughts were interrupted by the clatter of hooves behind her. She turned just in time to see a baseball bat connect with the top of her skull. She was knocked unconscious instantly.
Marigold awoke in a dark room with a dark figure above her. "Don't be so shaken…just remember this… go for the sides and legs…never the head…the head is too easy…you have brute strength on your side so use it… your small size provides a great advantage for quick movements with knives…alright kid… SHOW TIME!"
There was a bright flash and Marigold realized she was in the hospital room. Mr. Frost's personal patients room to be exact. Above her stood Frost and Scout. Marigold felt dizzy but could feel her legs restrained as well as her head.
"Ah awake at last…well then it's time for the procedure." Frost said with a resentful look in his eye.
"Will she suffer?" Scout said
"Not at all…well…maybe a little…too bad."
Scout placed a hoof on her, and tried to comfort her.
"Don't worry it's alright…you're gunna be alright." Scout couldn't help but cry. Mr. Frost took out a small syringe filled with a dark liquid, he searched for a vein on her leg and quickly dove the needle in. Marigold flinched and flailed against her restraint too no avail. She fell dead on the table. Scout looked at frost and the old stallion nodded. Scout untied his sister and hugged her lovingly. Marigold vomited and fell to the floor. She weaved between the table legs with lightning speed and rammed into frost with lightning speed, snapping his front legs in half. She grabbed a surgical knife from the table and dove it into the stallions eye socket. She stared down her big brother. Fear and disgust was causing her to tremble violently. While scout looked as if someone was committing a most heinous of all crimes, truly a look of pure disgust and hate but also one of pity for the poor lost soul. Marigold couldn't help it she just fumbled and ran out any door she could find. She managed to find her way to the front door. she slammed into it, expecting it to open. She rammed it repeatedly, then turned and practically obliterated it with a fierce buck from her hind legs. She ran outside and made her way to the first direction she saw. It was night and pure black, she could barely make out a house. The whole event started to sink into her mind and she trembled even worse, eventually her knee's gave out completely and she fell into a divot, halfway into the forest, and just an acre away from the hospital. Marigold couldn't hold herself up so she laid on her side. she vomited once and heavyheartedly pushed herself away from the puddle of blood and vomit.
"Oh god…oh god…mommy."
There were a few minutes of utter silence
"God had nothing to do with this…and you're mother isn't going to save you…in fact… I'd say she was the sole cause of all of this." A voice said almost if pleased by the events that just took place.
"Who are you.." Marigold tried to keep a low voice
"I am the feeling you get when behind a blade, I am the feeling you get when you stare into a fire, I am the feeling you get when you stand atop a high place and ponder whether or not to jump… But to you…I am a guardian angel."
"What?"
"Okay I'm gunna have to spell this out for you… I AM THE ONLY THING KEEPING YOU ALIVE!!! You see…you took a lot of poison and thanks to yours truly, it's not melting your insides…I mean…it is…but not fast enough to kill you."
Marigold slowly curled into the fetal position and began to cry.
"Oh come on… hey! stop it. ugh… its alright…we have each other and I wont let them take you away from me."
"I want my mommy…"
"Don't you see she caused this all… She hurt me… then she hurt you…she really…REALLY…hurt you."
"W…who? Rainbow Dash?"
"Ah…that’s right, you have faggot parents…it was…ummm…the pink one! that’s her."
"Mom! I hurt her. Is she alright?"
"Are you kidding me? you stabbed her in vital organs…she bled out… extremely painful…guts…blood…the whole shibam a bam."
"What!?"
"Joking! god!...you have a loud voice…they saved her barely…I swear…ever since they began healing with magic killing has gotten harder."
Marigold hit the ground crying. Marigold felt some pony prod at her side.
"Hey…quite crying…what are you sad about?"
"My mommy hates me…they all HATE ME!!!" Marigold looked around too yell some more at the satanic spirit but there was still nothing but a dark forest. Marigold heard yelling off in the distance…she wasn't that far from town.
"Better stop yelliiiing…their trying to find you."
Marigold ran over the hill to the town.
"Woah! Da fuck you doing!"
"I want my family."
"In that case you need to understand what's going on first."
"What do you mean?" Marigold stopped dead
"I can't exactly say but it will help… a lot…follow me."
"What are you?"
"A emotion? A pure feeling of hatred…something born in a lying whore who is going to pay! And you are going to help me!"
Marigold decided to duck behind a bush.
"where do I go?"
"Good girl…now get to the train station on the next town over…don't stop…don't pause."
With that Marigold and the voice set off into the night.

Back at the clinic
It was mere moments after Marigold had murdered Frost and fled the scene. Scout stood over his dead master…the one pony that had taken him under his wing and saved his family in their time of need.
"Rest easy old friend." Scout said with a look of shock and anger
Scout grabbed several bandages and a potion, then ran off to save his family. He ran fast with the last bit of his strength. He ran past several ponies who had came to the hospital to inspect the cause of all the noise. They looked bewildered as scout ran past, but he had no time to waste explain. scout burst through the door of his house. Rainbow was crying holding a wound on pinkies back. A dull tired look was on pinkies face, truly a look of the dimming lights of a life. Scout put the bandages in rainbows hooves, she pressed them hard onto the wound, Pinkie didn't even flinch.
"Did you keep pressure on the wound? Okay…It punctured her lung, we'll need to give her this."
Rainbow looked around the room. "Where's Mr. frost?" Scout paid no attention to the question.
"Okay…Mom, I need to get this liquid in your lungs…"
Scout jams the bottle into her mouth. Pinkie kicks a hoof. Scout responded by covering her mouth and nostrils. Pinkie began to panic. She flailed her hooves frantically, kicking for any chance at life. Scout took the bottle out and Pinkie began trying to get it all out of her lungs. She collapsed onto the kitchen floor, completely exhausted.
"There…*Huff*…that will heal her internal injuries, she will live."
Rainbow held pinkie close and sobbed. She managed to choke out a sentence.
"What happened?"
Scout got up and checked around the house.
"She got out…she killed Mr. frost and now she is probably after us."
Rainbow looked at him in pure horror. She couldn't say anything except.
"No…"
"Well what did you expect…you saw how bad she was getting before…I don't think she remembers anything so Marigold is still in there…somewhere."
"What now?"
"We try and survive."
A ponies hoof was heard on the door. This was then followed by forced entry. Two voices were heard.
"What the hell! why'd you break down their door!?"
"You didn't see what I saw sir!"
"If you slow down and tell me then ma-…dear god."
Two stallions walked into the kitchen and saw the bloody scene.
"Who's hurt? What happened?" the oldest looking one said in a rather wise voice.
"The same thing at the clinic!" a young rookie said…shaken by the whole ordeal.
The oldest one knelt down beside Pinkie and Rainbow.
"Is she…"
Scout shook his head
"No…but there is going to be more ponies hurt if you don't listen to me."
He addressed the oldest first. "Sergeant…round up everypony."
He addressed the youngest second. "Black berry I need you to keep watch."
Sergeant looked confused…this was the first death he's witnessed since the war. "Who did this? and why?"
Scout had a guilty look. "This is going to be hard to swallow…"
