Say, do you remember that one pony? Was in a mental ward, barks like a dog, all that?
Yeah, she's actually a insane scientist.
And currently under Nurse Redhearts, uh, 'care', she's tied up and hopefull kept far, faaar away from the rest of the world. Hopefully.
Applejack keeps a padlocked container with her files and classified information in her desk. So far, only she, Celestia and Sunset Shimmer - in her role as her protege - have access to this.
~~~ Lots of background history missing ~~~
Applejack 12 has established a semi-deep bond with the crazed scientist and assisted her in her release.
Currently, Screwloose is free from the mental instituition she was locked into. After proving that most of her bouts of insane during which people were assaulted were actually her crazy, direct way of dealing with their health problems, Nurse Redheart approved her release.
Now, in the company of Applejack 12 and Snake Eyes (formerly known as High Roller), she is on the way to meet her old employer, Fawntaine Industries, now under the rule of Pennydrop.
While looking for yet another job, he stumbled across this one. Being expendable-I mean, being of a 'unique' standing, he was assigned to be her caretaker. In time, he grew to be her favorite of the workers, which means that most likely she'll probably consider using Anesthesia later... she'll consider it, I said.
The orderly who worked before that met with an unfortunate fate, surprisingly unrelated to her in any way. He may be dead, but he's not quite 'gone', as it were. Whether that is actually his spirit sticking around to haunt her or just her going crazyier, it is hard to say. Sort of... not really, she's just nuts, but there's a decent chance this is unrelated to that... there's a chance.
- Screwloose seems to has a hoof fetish, which she loves to project onto 12.
