"Eyes are the windows to the soul" a letter written by Twilight Sparkle to Princess Celestia

(OST)

Dear Princess Celestia,

Over the months that Dean has lived in the library with me after we first met, I've decided that compiling information made from observing him go about his day here at the library. I wanted to get a more in-depth study on Humanity, but Dean was adamant about not being a part of any sort of study, saying he had enough of that from the Sages back home. Oh well, I won't force him to do anything.

Now, I should start by what anypony would think on first glance. On first glance you see this strange being, an air of mystery about him that just seems to make you naturally curious about him. When you combine the history of Avalonians, you have a pretty good opinion of what a human is. Though everypony knew what a human looked like, it was still amazing to see such noble creatures in this day and age without going into the Everfree forest. Sure some of the ruins of their cities were discovered as to preserve their culture, but the trip I took with Dean and the other humans was an incredibly educating one

When we found the lost city of Avalon, the scholar in me was demanding that I take notes, but... what we found inside killed whatever notion of taking notes that I felt. We were standing in a massive grave site of Humans when they... when they saved all of Equestria. Their king at the time, Adamantius, was described as an incredibly powerful human, one of the most powerful at the time.

But that's not what I want to tell you, no, when we entered Avalon, there were other humans there as well. Three men, Zachary, Mot, and... Nex. Dean once told me that the eyes are the windows to the soul, and tell a lot about a person. He often tells me that he is sometimes baffled by how large a ponies eyes are. I often tell him that it's strange to see someone with such small eyes as a humans. But... I didn't mention one thing. A humans eyes are so much more intense than a ponies... with just a glare, Nex was able to intimidate almost all of us. Something about his eyes was sharper, darker, and seemed to promise violence against all of my friends.

I've studied a ponies eyes, and I've only felt positive *emotions. I've never felt anything influencing me from a ponies eyes, be they unicorn or pegasus or Earth pony. Dean had shown this sort of gaze once, when he was fighting Nex. He seemed... I don't know, elated. Happy to be fighting. Reveling in the violence of it all. But when the fight was said and done, he seemed exhausted. On the trip back, he said he wished they could have resolved it without all the fighting. I raised my concerns, and he told me this.*

"I may seem like I enjoy a fight... and I will say that I do. But a fight to the death... killing is just a chore. It is shameful and unneeded when used upon the innocent, but necessary when done for the right cause. Now though... Killing is all that it is. A chore that is necessary."

I couldn't say anything to him afterwards. I just... I couldn't believe that the man I think of as another older brother and one of my friends... was so callous on the aspect of killing another living being. This brings me back to my original point, his eyes just seemed... Dead. No emotion, no feelings, just emptiness. I wanted to comfort him, but I didn't know how. He spent most of the trip back to Ponyville in silence, seemingly thinking to himself, and only replying in short sentences.

Princess... I think he has killed before. I think he has killed more humans than I can count. I have a feeling that he has, and that scares me. But... I don't fear Dean. I fear that he may go back to being that way again. To being uncaring to who he kills, and when he does it. I know he has a good side to him, I've seen it before! He has shown it to almost all of Ponyville whenever he meets somepony he doesn't know!

I have to show him that he has friends. That he can count on all of us to be there for him, should he need it.

I don't want him to feel alone anymore.
