DISCLAIMERS/NOTES
1. This is a fan fiction based on characters owned by DC Comics. I DO NOT OWN THEM. This is just for fun.
2. This is a femslash story. If you don't like that sort of thing, you won't like this.
3. Just a reminder: the Supergirl in this story is not Kara Zor-El, but the post-Crisis Matrix with an altered backstory. For more information, see Disclaimers/Notes for the first chapter.
FROM AFAR
He watched her from afar. Always from afar.
She had no idea how he felt about her. Why would she? To her, he was a beast, an animal. Something to be petted and ridden.
She had no idea her horse had the mind and soul of a man.
Comet watched Mae through the barn window. The perfect blonde was standing at the farmhouse letterbox, going through the Kent post. Condolences where still coming in for Jonathan, several months after his passing. His loss saddened Comet: Jonathan was a good man, who always treated him well.
As did Mae. Her love for all living things gave Comet renewed purpose, despite his situation.
Cursed by the witch Circe, Biron was transformed from a normal man into an equine. After wandering the lands for a long time, often contemplating suicide, he found himself at the Kent farm, where Supergirl came across him. From that moment, Biron was gone, instantly lost to the Girl of Steel; his physical body did not change the way he thought and felt. When the shapeshifter convinced the Kents to let her "keep him", he found happiness for the first time since his transformation. Naming him Comet - Biron did not mind, as his Human name was no longer relevant - Mae doted on him, always making sure he was well-fed and had regular exercise. Thanks to Mae's affection, Comet actually found a semblence of contentment. There was no way to communicate, no way for him to inform her of his true intelligence and identity, but her presence somehow made up for that.
The man-turned-horse was in love with Supergirl. And though he could never tell her, and nothing could ever happen, he was... "satisfied" was not the right word, but just being with her was enough. Besides, after Circe's curse Comet gave up on ever being happy again. So spending the rest of his days with the woman he secretly cherished - even in his accursed state - was more than he thought possible. He had accepted his lot.
But then she came along. And took his Mae from him.
Comet did not like Mary Batson. She seemed to take up all of Mae's time. The nights the Girl of Steel would spend tending to the stallion, feeding him or reshoeing his hooves... now she was spending with her. And it was even worse since the interloper relocated to the Kent farm. Martha had ear plugs at night; Comet had no such luxury. If the bedroom window was open, he could hear everything the hussy was doing with his Mae.
He detested Mary Batson. He hated her. He despised her. And worse of all... he could do nothing about it. Indeed, Comet knew what would happen if he outright attacked the bitch. Mae would pick her over him, and cast him out. Maybe even have him put down for being "dangerous". Worst case, Mary would say her stupid magic word and deal with him herself. Though no one was aware of his true nature, Comet had an inkling she knew he did not like her at all.
No, he could never attack the slut, but he could do something to make his torture almost bearable. He could make her miserable. Comet relished every chance he had at nudging Mary, brushing her aside or flatout walking into her and knocking her off her feet. And he refused to let her ride him. Initially he hoped his behaviour towards her would be "innocent" enough not to incur Mae's wrath, but rough enough to get Mary to go away and never come back. But no - the whore actually moved in. Curse her.
Comet came out of his musings at the sight of a sickeningly-familiar figure descending from the sky. Her. After a quick bolt of lightning, the arrivee rushed upto his Mae and engulfed her in a deep embrace. Comet felt bile in his throat at the sight of them. The sight of her being with his secret love in a way he could never be. It only fuelled his hatred and desire to see her actually dead.
He continued to watch from afar...
