It was around the same time Celestia came home in the other world that Twilight woke to the sound of talking. She opened her eyes sleepily to see Sunset sleeping peacefully. She smiled and inhaled the scent of lavenders. Twilight stretched and glanced back at the door. It was cracked. So that's where the talking came from.

Twilight got up and went to the door to close it so she could get some more sleep when she heard something that made her heart stop.

" She's unstable."

It was the doctor. Twilight peeked through the crack and saw Principal Celestia and the man.

" I had known for a long time, doctor. Ever since she came to Canterlot high," Celestia said.

The doctor shook his head and showed her some X rays. " This is a couple of scans on her brain. Right here in her Prefrontal Cortex, the part that controls emotions, it shows there's some damage. An important nerve has been disconnected somehow and it's very recent. Presumably, the nerve was severed when she hit her head hard on the floor when she passed out. What we found, however, was that the nerve had already been damaged and for years.

" I pulled up her medical records and the doctors from before have diagnosed her with autism. She has problems connecting with people emotionally, am I right? Does she have anger issues?"

Celestia nodded. " She has a history of easily getting riled up and has caused some problems at the school."

" I see. The damaged nerve controls how severe her emotions are. When it was damaged before it was cut, the signals from her Deep Limbic System to her Prefrontal Cortex was low and so, if she was feeling angry, her anger instantly was transformed to rage. Of course, since there was still a connection to her Deep Limbic System via signal, she eventually would calm down.

" I also found that her left eye has no sight whatsoever. Do you know how that happened? There are vital signs that that eye once was functional," the doctor said.

Principal Celestia shook her head.

The doctor sighed and flipped through some of the papers he had.

" Well, her Temporal Lobes, which is located in the temple right behind her eyes, are in control of memory, language learning, and mood stability. Now because of her left eye being completely at a loss pertaining to sight, her Temporal Lobe behind that particular eye has...malfunctioned. Especially since it's her left lobe, distress in that part of her brain has led to temper issues, aggression, and severe depression. All of which your student has been subject to."

Twilight stood frozen in the doorway. This was bad. Sunset was autistic? She had damage in her brain? And here was Celestia's other self standing there taking it like nothing phased her. Like nothing phased her one bit.

Everything changed in just that one moment. The whole Sunset is evil story became a lie to Twilight. If Celestia's other self could stand there as if everything she just heard was nothing bad and traumatizing, then the Celestia she knew couldn't be any different. She had no heart.

The doctor cleared his throat and patted Principal Celestia on the shoulder. " I'm so very sorry. Your student here will have to have a psychiatrist at the school and visit them every day. She'll also have to take medicine twice a day for her condition. A miracle will have to happen in order to help her. I'm afraid your student won't be the same as she had been..."

He squeezed her shoulder and walked away. Principal Celestia stood there for a while before turning toward the door. Twilight dove back to her chair and pretended to sleep. The woman opened the door and looked in on them.

Celestia just stood there for a minute before turning away and leaving.

Twilight stared at where she had stood. If only she had known Sunset Shimmer would be hurt.
