Here is the real deviant art description:

Scootaloo: The only survivor of the Rainbow Factory’s torture. Scootaloo has sought refuge by Fluttershy and Twilight, traveling between the two homes through a tunnel. They were one of the only things that felt like an actual family to her. However upon finding out that Fluttershy has a vampiric counterpart Flutterbat. The fear of almost being fed on scared her, triggering her PTSD. She ran away, devastating Fluttershy. For a while she became a drifter, traveling from town to town. Eventually in her early teen years she encountered Mane allgood and Snap Shutter. Equestrian Famous Monster hunters and Artifact Specialists. They agreed to take her in for their teaching, claiming that they view her as their daughter. She was weary at first but they did treat her well in the beginning. It was a process for them to gain her trust. Once they did they leaned her into more dangerous situations, using her as bait while treating it like they didn’t intend on that result. Using their manipulative skills to convince her that they never meant to put her in harm’s way. Eventually she picks up on their schemes and manipulation, shortly after receiving her cutie mark running from a set trap meant for the monster she got stuck in the cross hairs of. She planned and had them fall on one of their own traps. However one fateful day Mane and Snap fell into a pit trap asking for Scootaloo to help them as they gripped onto the ledge. She stood there and watched them with static eyes as they eventually got tired and fell to their deaths. After this experience, it led to Scootaloo returning back to the only ponies she viewed as her parents. Twilight Sparkle and Fluttershy. They are happy to have her back.

I’m sorry, I commented on the wrong image

Apple Bloom: Accomplice and apprentice of Pinkie Pie. Has become conditioned to be desensitized to death. She was taught shortly after AJ turned undead. As years pass of dancing with death, Apple Bloom has been exploring different methods and cities to kill in since The Cake’s business was expanding. As a precaution her sister gave her a worm that would keep her immune to the parasitic worm’s functions so she cannot be turned mindless. She has always had a crush on Sweetie Belle, ever since they were kids but never acted on it because of Sweetie’s affections to Button Mash. Apple Bloom just thought he was a little welp but if Sweetie liked him then she’ll behave for her. Later as life went down the line, Apple Bloom tried her best to move on from it. However one day Sweetie called her crying, trying to find her husband. She was there to console her whenever Sweetie discovered he moved in with an old crush of his. She offers to kill him but Sweetie refuses and wishes to accomplish that herself. Later on Apple Bloom accidentally confesses her feelings to Sweetie Belle. They end up getting together and start dating.
