After the defeat of the changeling army lingkind retreated, instantly leaving Equestria in fear and disorder.

Well, most of it.

At the time of the attack one changeling with a broken wing was separated from the other ones by coincidence. Left alone in the Everfree Forest near Canterlot, he didn't notice his fellows starting to invade the city. When they finally fleed he already got lost in the woods.

As a consequence he was disconnected from the changeling's collective mind. Otherwise unable to survive he started to decide individually developing an own personality consciously observing his surroundings. He managed to set up a camp, collected enough food and found a lake nearby. After he considerd himself save he began to reflect about his situation which led him finally to thinking about a possible name for him - and he called himself 'Sole'.

Once his wing was healed, he travelled around until one day he detected the presence of other changelings far in the north.

Happily, he tried to establish a connection, but he noticed quickly that it wasn't the same experience anymore. He was rather an observer than a part of the community which was the essence of his life making him feel whole only a few months ago.

His short visit to the hive mind was not unseen. When he pitched up his camp that evening, he was captured by a small troop of changeling soldiers. He didn't resist them and finally was taken to a hidden settling in the mountains.

After days in the dungeon he was taken to Chrysalis. They had a talk in the queen's throne room; she suggested a deal:

Sole was allowed to live freely as long as he promised he would stay near Ponyville and report on the situation. If he breaks the promise, he'd be declared an outlaw. He'd suit the role as a spy far from the hive mind best since he didn't require a constant link.

And because he was still loyal to his queen and didn't like the idea of spending his whole life in prison he accepted it.

He went back to Equestria and observed the 'Elements of Harmony' not seeing anything unusual happen until one day in the summer:

He wanders around the Apple family's farm - entering their property would have been far too dangerous, since there was still the chance of getting spotted.

"Is this Twilight's new pet?" he asks himself as he sees a tall bipedal being wearing some sort of brown clothing. Its mane is black and well cut, its face shape is flatter than an usual pony face, instead of fur skin covers its body. It seems to be a male.

"Oh, it is able to speak! Does it feature pony-like intelligence?"

Sole tries to get nearer when suddenly a scream disturbs the quietness of the place. He's astonished by how a little filly (Her name is Applebloom, right?) on a apple tree is saved from falling at the ground with a jump sheet - which, he can swear, wasn't at that place just seconds ago. This happened without any help of Twilight's magic, as far as he can tell. Then he listens to the talk between Twilight, the bipedal and the filly.

"Girls come here! Applebloom, why did you do this?"

The addressed pony hides behind the exclaiming mare. She's obviously afraid of the bipedal.

"He saved you!"

"He wasn't able to prevent her falling in the first place, was he?" Sole wonders.

Two additional fillies join their group keeping distance to the unknown being.

"Come on. Do you think that jump sheet set up itself. It's Jack, the special guest, a human, I mentioned before. He did it again, he created it to save you from getting injured..."

"Did she just mean what I think she means?" asks Sole himself.

"I told you about his special ability to create matter."

Jack approaches the filly and kneels down to match her height.

"I didn't intended to hurt you, in fact I worried about you. You remembered me of someone," he says with a warm voice and a small smile.

"Umm, thank ya, I guess," Applebloom says shyly.

The other fillies get closer. In the next minutes Sole watches them overcoming tensions until they finally split up.

"This will be interesting to the Queen."
