As far as foals go, Vapor Trail and Sky Stinger constituted polar opposites. Sky was loud, pretty brash, and constantly trying to get attention from his parents (which he rarely received, as he had to compete with four pretty noisy siblings). Vapor, on the other hand, was an only foal (although she had once used the word 'child'. What is a child? I've never seen one), and as a result her parents constantly bombarded her with love and affection, getting her attention at practically any occasion and trying to keep her engaged no matter what. Let us flash forward to the day she and Sky met. It was a beautiful day. The sun shone, the sky was blue, and some clouds floated about in the sky. But Vapor wasn't happy. She sat on a cloud, looking down upon the Stinger family playing in the backyard. She had no siblings, so had nobody to share that sort of bond or affection with.
Just then, two familiar voices echoed from down below, where her home was.
"Vapor Trail!" called the voice of her mother, Twirly Whirly. "Where are you? Do you need a snack? Do you wanna do homework?"
This was then followed by her father, Steer Straight. "Or we can just spend some time together! All day is never enough!"
Vapor rolled her eyes. As much as she loved them, she did find their constant attention seeking antics extremely irritating, especially as she saw Sky fail for the one hundredth time to get the attention of his parents.
"Mom, Dad, I'm here! Look, look, look- look- look- look, hey! Mom, Dad, can you see?" Sky was trying to pull off a flipping loop, but didn't have the wing strength to pull himself into it and clear the angle in time. He was just about to give up, when Vapor decided to make her move. She hovered in behind him, and flapped her wings forward, giving Sky just enough wind to be propelled upwards and clear the loop. As he stopped, clearly, astonished that he had somehow pulled it off, Vapor spoke up again.
"Whoa, that was amazing!"
Sky turned around to see Vapor sitting there. "How long have you been there?" he asked.
"A little while," Vapor replied. "But I think we both have what the other needs. A friend. I don't know anybo- anypony my age, and you don't seem to be noticed by your parents or siblings. So, what do you say? Friends?"
Sky whizzed in and hoofbumped her. "Yeah! Friends forever!"
Flying through the skies, defying gravity and pulling off insane stunts and fast maneuvers together, gave both of them what they wanted. As the years passed, their bond only grew stronger, with their closeness improving their flying as the whizzed through the air and soared over the hills and valleys of Stratusburg. After graduating from high school, both of them (by now a stallion and a mare respectively rather than a filly or a colt) applied to join the Wonderbolt Academy. To both their surprise, both of them had got into the Academy, although it was here things had begun to go wrong.
Sky's overconfidence had only seemed to get worse, with him paying no attention to the lessons on wing angles, wind speed, propulsion, air resistance, and other critical things he needed to know in order to fly well. Vapor, on the other hoof, was worried that somepony would spot what she was doing in helping him. And they did. Twilight Sparkle and Rainbow Dash had confronted her over it in the locker room, and she had told them the story of their foalhood (although she did make a slipup of making reference to 'kids' and 'only child', which somehow neither Twilight nor Rainbow noticed). Attempts to solve the problem through increased extreme training hadn't worked, and eventually Vapor had openly told Sky what she had been doing. He had brushed it off at first as nonsense, but when he tried to pull off his signature maneuver, solo, he had rapidly learned of his folly and hit the ground like a ton of bricks. He certainly felt like he had hit a ton of bricks afterwards, as from then on he'd berated her about lying to him and then flown off, wishing he had never been her friend.
Just as Twilight and Rainbow had created the mess, they fixed it, getting them to reconcile and ultimately pass their trials. They had gone through training, and were now fully fledged Wonderbolts, flying through the skies in blue and yellow, making their mark and keeping the skies clean and cloud free. And now, the happiest day of her life was near. Her chance to marry the stallion of her dreams. There was just a bit of a problem, I'm sorry to say.
Ever since she was a foal, just like the one she had gotten in the cafe in Stratusburg, she had had these strange recollections of strange things. These recollections were of a big place on an island, but not Sodor, where a thing was in a park late at night and there were some other strange things, such as a box and a trail of odd green stuff running on a pathway. She'd never really put much stock into these odd visions though, as they seemed so random and meaningless to her. Besides, she had bigger things to think about.
The night before her wedding, she had stayed at her parent's house, as of course it is bad luck for the bridge and groom to be together before the wedding itself, to be exact 24 hours before the wedding itself. Early that morning, she was taken off to the dressing room, where Rarity was waiting (a friend of Twilight's, a favor had been called in) to fit her into something that looked simply magnificent. But if you want to learn what that something that was simply magnificent was, you'll need to wait until tomorrow, when the next chapter arrives.
