MLP Future: Prince of Unity

In the sky city of Cloudsdale, a little skyblue pegasus with a short silver mane was wandering around after leaving school, not on the usual path to his home. He felt he needed to clear his mind of what all the other fillies kept telling him.
"Agh! Why don't I have a cutie mark yet!?" Yells the young colt. His problem was actually similar to alot of other ponies at his age. The term 'blank flank' seemed pretty common for many bullies to use on young fillies. However, this little pegasus has a deeper wound that the older ponies always poked at.
As the pegasus wandered, he noticed it was beginning to get dark. Princess Celestia was lowering the sun so her sister, Princess Luna, could bring out the moon and go out helping all ponies in their dreams.
"Oh, I guess I should head home before daddy and my cousin get worried." Sighing, he takes off to the sky, looking for a fast route to his home.
"Oh! Look who is here, guys! It's Dash's little Blank Flank of a cousin, Sky Heart!"
Sky looks down, seeing an older midnight blue pegasus with a blonde mane fly up, getting in his way. A few other pegasi fly up as well, surrounding the smaller pegasus colt.
"C'mon guys! I don't want to deal with you right now! I have to get home!" yells Sky. He tries to get by, but it pushed back into two of the other ponies, both grabbing his legs.
"Awww. Are you trying to get home so you can play with your dollys? Or is it because you want to talk to mommy? Oh! I forgot. You don't have a mommy!" Laughs the midnight blue colt. He then headbutts Sky in the chest, making him lose all his air in his lungs. This action also makes the other ponies let go, and Sky drops down, hitting his head on a glass window of a shop.
"Um, Thunder? I don't think that was very-" says one of the pegasi, before Thunder cuts him off.
"I'm gonna stop you there. He had it coming, after all. Thinking he could just chat with my mare-friend and not expect any kind of punishment? Heheheh. He's just getting a warm-up so far."
He flies down, followed begrudgingly by his friends. Sky tries to get up, breathing for air. He then notices he is surrounded again, Thunder being closer to him than the others.
"Now, what kind of pain should I give this mare-friend stealer?" He mocks. Sky struggles to get up, crying a bit.
"I wasn't trying to take your mare-friend, Thunder! I just wanted to become simple friends with her!" Cries out Sky. Unfortunately, he is bucked into the wall he was next to, Thunder laughing.
"Well, I guess you should have figured out you were out of her league! Now, time for your wake up call!"
Thunder starts to charge at Sky, smiling evilly as he was aiming to break his legs. That is until a fist of wind started to blow, throwing him off balance. The other pegasi colts look up, seeing dark clouds begin forming in a swirl. Panicking, they fly off to their respective homes. Unfortunately, Thunder got furious at this because of a little 'bad luck.'
"Hey! Get back here you cowards!" He yells at them, not getting any response back. He furiously huffs, turning back to Sky.
Sky was shaking, scared of what was going to come. He was oblivious to the unusual weather that had blown Thunder off target.
"Looks like I have to do this all by myself!" Yells Thunder, jumping into the air and diving at Sky. Sky yells out, terrified. Then, Sky's eyes turn completely white, glowing with radiance that slightly blinded Thunder. The next thing was a blue lightning bolt shooting down from the unusual stormcloud, striking Sky on his forehead.
"Well," says Thunder, backing away just in time to avoid the lightning, "I guess my job is....." He then notices Sky wasn't hurt at all.
"H-how!?" He yells out, only to get blown back by a white aura-like field and getting knocked out on contact with a building.

"Nnngh. Wha? What happened?" Sky asks himself. He realizes he is in some sort of void.
"H-hello?" He calls out. Soon a light appears before him, and out of it steps a blue alicorn with a sparkling blue mane. It was Princess Luna.
"Hello, little one. Are you feeling okay?" She asks, showing a bit of worry for the pegasi filly.
"Huh? Of, yes I'm fine. Thank you Princess. But....why are you here? And where IS here?" Asks a confused Sky. Princess Luna sighs, not knowing how to say this.
"Well, Sacred Sky Heart, we are in your dreamscape. As to where....you are in a intensive care hospital ward in Cloudsdale." Explained Princess Luna. Sky was, putting it mildly, shocked.
"Wh-wh-WHAT!?" Shouts Sky, now in full panic mode.
"What happened!? How!? Why!? Has it been only a day!? A week!?" He rants on, flying around in a streak of silver.
"Be calm little one. It hasn't been a week." Princess Luna calmly tells Sky, to which he slightly slows down.
"As to what happened, you were being bullied by a colt named simply Thunder. Unfortunately, nopony knows how the both of you were hurt. He was released yesterday from the hospital, but I finally got a chance to contact you right now." She continues, but Sky saddens, realizing he somehow hurt the biggest bully in Cloudsdale High. He soon feels a hoof on his shoulder, and sees Luna pull him into a hug.
"Do not let this get to you, young Sky Heart. I know you wouldn't do such a thing on purpose. How you did it, though... That remains unclear."
"I....I don't know what happened either. All I remember was I panicked, then everything went white! That's all I remember until you came to me now." Sky explained, not feeling any better. Luna holds Sky closer, comforting him the best she could.
"I too know what it feels like, to have done something unintentionally and blaming myself like it was all my fault. However," she lets go of Sky, smiling at him, "your cousin Rainbow Dash, along with her friends, reminded me that if it was not on purpose, you mustn't let it weigh you down."
Sky couldn't help but look at the princess of the night, surprised. He knew she was known previously as Nightmare Moon until Rainbow Dash and her friends defeated her with the Elements of Harmony. What did she do to feel she something wrong when it was an accident? Before he could ask, soft murmurs could be heard.
"Looks to me you are finally about to wake up." Says a sincere smiling Luna. "In case you continue to feel this way, head to the little town of Ponyville. I'm sure my sister's protegé and the princess of friendship will help you. Especially since she just opened her School of Friendship. I must take my leave now. I do hope you take my advice, Sacred Sky Heart." Luna ruffles Sky's mane before walking into a light disappearing with his surroundings.

"Wha-!?" Sky shoots up out of the bed, looking around. He notices he is surrounded by hospital equipment, an IV in his arm. Over in the chairs of his hospital room laid his father and cousin. Dash, overhearing Sky waking up, speeds over and hugs him right.
"Ack! Cuz....can't....breathe.....!" He gasps, making Rainbow Dash let go. She was crying.
"Heheh. Sorry little cuz. I'm....I'm just glad you're okay." Stutters Rainbow, trying to fight more tears from coming. Sky smiles a little, hugging her back. He then remembers his conversation with Princess Luna.
"Hey Dash?" Sky looks to Dash, feeling nervous.
"Yeah Sky?" She looks at him, smiling as she finally stopped crying.
"Um..... can you help me enroll at the School of Friendship?"
