Leaning on the wall, a filly stared at a curtain in a small window, her horn began glowing and she opened it and peered outside like she was waiting for something. Her coat of lavender standing out against the golden wall, and rose carpet. She snuggled into the white curtains, tearing up. She couldn't believe what was happening, she didn't want it to happen but she had to accept destiny no matter how hard it was too. She closed her sliver eyes, thinking about what had been told to her the night before.

She slowly moved from the window, upon seeing a pony walk up to her home, with two things resting on it's back. From her position, the filly couldn't see what gender the pony was, despite already knowing that the pony was a mare, nor could she tell what the objects were and she personally didn't want to know. Brushing a lavender hoof through her orange mane, the filly continued to think for a little while.

''...Why, daddy?....Why did you do this to me and mommy....'' The small, weak voice emitted from the filly's lips as her tears continued to form in her eyes, she hated it.

She stumbled away from the window, after noticing that the mare was gone, and walked over to the long staircase and look into the hallway below from her chosen seat next to the balcony. She stared down, with a lack of interest in her eyes. She had expected the mare, but what she hadn't expected was the small pony that came with, a baby. The only babies that the filly had ever seen was literally herself and her parents in family albums. She noticed they were speaking and choose to listen into their conversation, trying to catch all of it into her small ears.

''How's your daughter taking it, Quartz?'' asked the mare, to the stallion that stood in the room.

''Well, when I told her last night, she seem pretty shocked and wary but she'll get over it. What about the little one here?'' asked Quartz, the lilac filly's father.

The filly looked carefully in her father's line of vision, seeing that he was staring at the foal. She decided to simply take in the foal's appearance and saw a cream filly with a white mane and tail. She couldn't see the filly's eyes from the distance she was away from the infant. She did however think that purple would be a nice color for those eyes. She then saw then resting under the filly's mane was a pair of beautiful creamy white wings. White? White wings were common in Equestria but only when attached to a white body. To have wings of a different color to the body was weird to say the least.

''....Well, um....About that.'' mumbled the mare, like she had forgotten to say something to Quartz. ''My daughter isn't a infant.''

'What' was what the filly wanted to scream out loud. How in Equestria did the mare think that her daughter wasn't a infant, how old was she actually thinking. It didn't make sense, but before she blew her cover, her father stepped in with the question. ''If she's not a baby, how old is she and how is she that small?''

''She's only seven years old, but has seen things that most fillies shouldn't. And as for why she looks to be a foal, well I took her to the hospital a few weeks ago and they diagnosed her with a growth disorder that forces her body's age to go up very slowly. So well she may be in written and mental focus 7, her physically age is only of that of a 2 year old. Angel Dust has had problems in her genes since she was a baby so it's not much of a surprise.....more of a concern if anything.''

''I see. Well, let do our best to raise her without her feeling pain anymore. Right, Golden Feather?''

''Right. Dusty, come here please.''

The small filly didn't move but looked back at her mother for a moment. She didn't speak or anything, simply got to her hooves and slowly and obediently, walked over. She didn't say a word, and look at her mother with sad purple eyes. As soon as she was standing just in front of her mother did words come out. ''Yes, mother?''

''Sweetie, I have to go back to our old house for a little bit so stay here with your new daddy for me. Just for a few days, alright? You can also meet your sister that way.''

Angel Dust nodded, cautiously as she glanced at the balcony. The filly's eyes focused and she noticed the lilac filly sat behind the bars. She didn't point her out however, much to the lilac filly's surprise, and simply stayed quiet. The filly gritted her teeth a little, not because she wasn't pointed out but because of the entire situation. 'I hate this....papa, you told mama that you wouldn't remarry but you betray her and choose to marry again. And now you expect me to get along with a sister, which I didn't even know about till today and to top it all off, she's a 'false foal'!?'

She didn't get to continue thinking, when a call was made out. ''Ribbon Song, I need you to come downstairs if you will.'' It was her father, and she had nothing to do but obey. She wasn't as willing as the other filly to commands like this, but she had no other choose. In this house, it was father's rules and that was that.

''Yes father.'' said the filly, as she came out of hiding and walked slowly down the huge stairs. She made it to the bottom and walked over to her father and apparently new mother and sister.

''So, your the famous Ribbon Song that I been hearing about. When your father told me that you were ten years old, I wasn't expected such a mature, little filly.'' said Golden Feather, with a smile. She glanced down at Angel Dust. ''Sweetie, introduce yourself to her after me, would you? My name is Golden Feather and in a few weeks time, I'll be your step-mom.''

''.....Angel Dust....n-nice to m-meet you...'' The filly's voice wasn't calm or anything, she was definitely frighten by Ribbon's harsh glare. She didn't know what to do, she was obedient because she was scared of a consequences despite knowing her mother would never, in a million years, harm her in any way or form.

'Father, are you really sure about raising this foal? She's such a pushover!' cried Ribbon, internally. She kept her calm and collect expression though and introduced herself, with a harsh tone. ''My name is Ribbon Song, ten years old and I guess I'll be your older sister, just don't call me 'sis' or anything other then my full name.''

The meeting ended with that, awkward as hell with the younger sister nervous and the older sister intimidating. The parents were even awkward to the point that they were actually worried that this wouldn't work out. Angel simply weakly stared at her older step-sister, worried if this was how is was always going to be.

Author's Note

By the way, just because Ribbon Song is leading her doesn't mean she is the main character, Angel Dust is by default. I prefer her, she was the original OC for this story before I changed my mind. By the way, just to ask. Should this be either a simply sibling relationship story or a pseudo-incest, love story? Just asking.
