The CMC mission did not wind up being an ordinary short-term mission - it took several years.
During that time, reparations and amendments were made, one by one. Scootaloo continued to have nightmares about being bullied, but whenever she did, she would talk them out with her friends, and in doing so, felt the weight and fatigue that often followed her nightmares lift from her head. Scootaloo felt lighter.
Diamond Tiara and Silver Spoon appeared happier too. They were finally fully accepted members of the CMCs. In a way, they were CMCs too: They had needed to find the true meaning of their cutie marks.
Diamond Tiara, as she had mentioned when she was first reformed, had a special talent for getting other ponies to do what she wanted - which meant, getting the CMCs to be her friends so that she could help them, and become the pony she wanted to be. This included getting Scootaloo to forgive her, and herself, so that she could fly.
Apparently, Silver Spoon’s cutie mark could be used for knowing what to do in certain situations. She had been born with a silver spoon in her mouth, which meant she was born into a life of being rich. However, this also meant that she came into the world prepared to take on certain tasks; tasks which involved helping other ponies in her own way.
In this case, that had meant encouraging Diamond Tiara to follow her dreams in order to amend her personal feelings, and her relationship with the CMCs. Silver Spoon was a hench pony, but now for a good cause.
As for Scootaloo learning to fly, the actual work process to help Scootaloo fly resumed. As her self confidence grew, Scootaloo found that she was less timid when flying, and found that, despite her small wings, she had some ability - more than she had let on - that only needed to be enhanced.
First, Scootaloo listened to Applebloom and ate foods which were known by Earth Pony experts to promote strength, agility, and growth. The combination of healthy food, and the compassion and caring that Scootaloo had always craved, actually helped her wings to grow.
Sweetie Belle didn’t use a growth spell after all. What she did was levitate Scootaloo at times, giving her a chance to practice being in the air, and using her wings to keep herself up. The process was slow, and there were a lot of cuts and bruises on the way, but with Scootaloo’s growing self-confidence and dwindling memories of being bullied for being unable to fly, progress became achievable.
It was the combination of healthy food, a touch of magic, and friends to rely on for emotional healing and confidence building that got Scootaloo to gradually achieve her dream. In two years, she could fly all the way up to a tree and back. From there, the process happened more quickly.
One day, she flew up to Cloudsdale and saw Rainbow Dash, who looked thrilled to see Scootaloo finally flying. Now that Scootaloo could fly, she could have some real lessons with Rainbow Dash about tricks.
Scootaloo’s wings grew to be large and beautiful, and even a bit tinged with rainbow colours with respect to the standard CMC multicoloured cutie-mark emblem. When she turned eighteen, Rainbow Dash taught Scootaloo how to control the weather by moving clouds. Scootaloo found she could move them with her wings alone, being fast just like she had been on her scooter when she was a filly.
Scootaloo became known as the thunder rider of Cloudsdale; the pegasus with the most agility when it came to clearing the weather. Scootaloo did it with compassion to help other ponies; something she learned when becoming a Cutie Mark Crusader.
Meanwhile, Sweetie Belle became stronger with magic and at times, she could even help Scootaloo control the weather with spells. Because of this, the two of them could work as a team to stop severe weather disasters; they were helping the world, together.
Applebloom inherited the farm from her sister, and developed a food-research team with Diamond Tiara and Silver Spoon. The three of them farmed food and researched natural ways to help others. Helped the world by providing it with delicious food that could help ponies in predicaments such as Scootaloo’s.
They were all cutie mark crusaders, who had discovered themselves and helped other ponies. And they couldn’t have done it without each other.
The End
