"But Princess, he's intelligent!"
Celestia wheeled around, looking Twilight straight in the face.
"It is not your call, Twilight Sparkle!"
The Princess of the Sun's eyes were filled with rage. Twilight had never seen her so angry...
"But Princess, he was scared out of his mind! He asked for our help!"
Celestia brought her hoof down, the ornamental golden show creating a more-than-audible slam on the marble floor of her chambers.
"I brought it here because it attacked us! It destroyed part of the Everfree Forest, and therefore, it does not deserve a bed! It deserves captivity for attacking such a pure world-it is truly an animal."
Each time she said the word 'it', her voice grew steadily louder, until it was almost as loud as the Royal Canterlot Voice. However, on the last 'it', her voice was reduced to a biting whisper, dripping with venom.
Fluttershy was shaking out of fear, her eyes closed. She seemed to be struggling against her self to run out of the door. Her five friends surrounded her, trying to comfort her.
And then some hot-headed pony called out.
"Celestia, that's...ridiculous!"
Everypony, except Celestia, wheeled around in surprise at the accusation, as well as how rude it was.
However, what shocked everypony more than the statement itself was who it had come from.
Her five friends moved out of the way, not wanting to get in the way of the conversation that was sure to ensue.

Pinkie Pie wasn't laughing at all, she couldn't laugh even if she wanted to. The pink, sugar-infused party pony sat still for once, genuinely scared at the idea of what would become of her friend.

Twilight's eyes were bugging out. The lavender unicorn couldn't believe her ears, or her eyes. Her mane was quickly getting unkempt, and she was visibly shaking, horrified at what was about to happen.

Rainbow Dash's jaw hung open, her eyes small. She sat on her haunches, too astounded to fly, her rainbow mane creating a projection of colors on the white tiled floor.

Applejack stared in earnest, shocked by the sight before her. Her hat fell off, making an audible click on the tile floor. She ignored it, too stunned by what she saw to pick it up.

Rarity tore her eyes away from her...magnificent tail, which had just changed colors to white, whiter than the white marble tiles surrounding her, when she beheld the sight before her.

Spike tore his eyes away from Rarity, his body shaking, his tail straight and his scales pulling back in fear for his friend.

Celestia swiveled in fury, her face practically red. Her rage was palpable, her gaseous mane as rigid as a steel sword, her mouth open to shout out a royal 'how dare you'.
She stopped in her tracks, the words hanging dead on her tongue.

In the center of the ponies stood a yellow Pegasus with a pink mane, her normally gentle, scared eyes narrowed into an infamous Stare.

"He's a living being! You have no right to shove him in a cage and keep him unconscious with magic! I demand that he has a bed, and that we help him get back to his home. You didn't see how scared he was! He was scared out of his mind, literally! He was going insane!"

Fluttershy advanced slowly, her wings open in a menacing fashion. Celestia's eyes became pin pricks of fear, and she moved back, her oriental golden hoof shoes clacking on the marble floor.
"I demand that he is removed from that horrible cage at once and given a proper bed."
Celestia simply nodded. Fluttershy was simply horrifying when she was angry, and Celestia was simply horrified. She felt as though she was a subject being told off by a Princess...
"Wh---whatever you say, F-f-f-f-fluttershy..."
The stuttering of her name snapped her back to reality, and she quickly knelt down in fear, her yellow body quaking, sending her pink tail into spasms.
"P-please...don't arrest me...I'm s-s-s-s-so sorry...."
The small sound of dripping tears was completely audible in the complete silence.
Celestia stood, staring at the Pegasus with a mix of respect, anger, and self-hate.
"No, Fluttershy...It is I who should be saying sorry. I know how much it takes for you to break out the..." Celestia swallowed, the eyes of anger still present in her mind. "the...Stare. I realize now that I must have been...horrible. Horrible to push you to that point. I am truly sorry, my faithful subject, and I thank you for reminding me that every living being deserves a second chance."
She stood tall, looking down at the now-still Fluttershy with a small smile. Her six friends immediately ran over, crowding her with hugs and shouts of how amazingly brave she was. Fluttershy simply blushed, the red spots growing deeper in shade when Rainbow Dash set out a truly rare proclamation that didn't ingratiate her own skills.
"Man, I never would've been able to do that, Fluttersy!"
Fluttershy let out a small chuckle.
"Spike, take a note, please!"
Spike pulled himself out of the huddle on Fluttershy, accepting a teleported quill and scroll, courtesy of Celestia.
"Will do!"
Celestia dictated the following to Spike:

"I declare that Twilight Sparkle, Applejack, Pinkie Pie, Rainbow Dash, Rarity, and Fluttershy are to observe the ways of this creature called 'human', and to befriend him.

"I also declare that he is to help my six little ponies in matters big and small, and that they come to him with problems. He will stay with Twilight Sparkle, and will tell her his reactions to the days' work and his interactions with Twilight and her friends.

"However, I also demand that by the end of this month, Twilight sends me a full description of all of his possessions and their purposes, which are stored in a burlap bag.

"And I also declare that he receive weekly psychological attention from Fluttershy, and should he want to talk to both Fluttershy and somepony else, the other pony must attend his next session.

"Lastly, if he proves himself as a faithful friend and a civil being, he shall be rewarded with full citizenship in all of Equestria."
Spike finished writing it down, the large words giving him some halt, such as 'psychological'. But, he finished nonetheless, and handed it to Celestia, who made it an Official Canterlot Document (OCD) through a complex process.
She impaled the paper on her horn, her magic coursing through it. It vanished with a small pop.
Fluttershy smiled at the Princess, her eyes filled with tears.
------------------------------------------------------------------------------------
I woke up at the sound of voices.
Celestia was fighting with Twilight Sparkle.
I didn't dare open my eyes, the events of the previous day flying back to me.
One second, at robotics, the next second, in Equestria?
I wrestled the issue for a good five minutes, the questions roiling in the black sea of impending insanity.
And that's when I realized. I was emulating the idea of insanity: the idea that one tries the same thing over and over again, expecting the same results that they had the first time. I expected an explanation to be clear to me. That constant searching, that never ending denial of events until I found a reasonable...well, reason (sorry for the bad pun) would send me off of the unstable cliff of sanity I stood upon, the roiling, dark depths of insanity greedily awaiting my arrival.
I decided to go with it, and that I would search for a reason when I got back home.
Maybe this place is real...maybe I'm really in a world of talking ponies...
It gave me pause. I had rejected it before, that was all I had been trying to do...reject the idea that I was actually in a world of talking ponies. Instead, this time I tried to view it as though it was real.
If this world is real...then there is no war going on...there's no impending threat of terrorism...no economic struggle over oil...no homeless people in the dirty streets of Manhattan...
The idea gratified me. It was an idea I hadn't thought of.
A world devoid of pain...even if this world isn't real...even if there is a way to return to Earth...do I really want to go back to it? Where the people of pure good are crushed by the waves of corruption, the waves of war...
The word 'war' unlocked hidden memories. Images of Grand Central Station, once in its beauty, now burning.
But nothing else. Just the image of burning buildings.
No...I don't. I don't want to go back to a world of beauty, in which that beauty is always on the edge, threatened by those who would see it destroyed or exploited...
I steeled my nerves.
And I jumped.
I blissfully accepted the dark waves of the roiling sea of insanity.
Am I doing what's right...by choosing to stay here? Am I doing what's right by choosing to believe that this place is real?
As the violent waves of the dark sea of insanity crushed the cliff of sanity that I had once stood upon, it crushed my questions, replacing them instead with answers.
I came here to be given a second chance. To escape the pain. Something chose me...or someone. I don't know why, and I honestly don't care why. Something or someone chose to spare me, and sent me to Equestria...
A single tear streaked down my face, invisible to the six ponies, Alicorn, and baby dragon I could hear behind me.
This...this is where I've always wanted to be, consciously or not...
When I heard that I was to be taking residence in Ponyville, the thin boundary between 'belonging' and 'longing' broke.
This...this is my home.

Footnote: Hey! Author person thing here.
So, how do you like it so far? I actually just wrote this in about two hours, which proves how much of seat of the pants this is...
Anyway, this went through about three iterations. In the first, Peter was on display in a Canterlot zoo.
In the second, Celestia and Peter turned metal head, rocking out to Deadmau5 (stupid, right?)
And finally, in this one, I decided to make it happy. And make sense.
What's that? You expected insanity to be associated with fury and grief?
Well, when willfully accepted, the Seas of Insanity can be gentle.
However, that ride can get a bit bumpy.
