This is where the party's at! *stops singing*
Oh, hello...umm...I didn't recognize you all, it has been a loooooooonnnnnnggggggg time. ;_; Which I apologise for. I hope to get more written now that I'm back on the game (for now)!
Dash stood in front of me and held her wing out, trying to protect me. I really love you, Dashie.
"We need to talk," a white alicorn paraded towards us, "my student Twilight Sparkle got her story a little…mixed up."
I slowly pushed Dash's wing aside, looking into Celestia's eyes, "Is that so?"
She smiled, "Very," looking into the late afternoon sun she giggled, "I'm sorry about the hassle, Twilight told the incident and I know you're not to blame. She'd like to apologise and give you this," her giggle soon became laughter until streams of tears came and she handed me a book, "she thought it'd make more sense if you studied it well, being as young as you are. I've read over the book and confirmed with her that it's appropriate."
I looked down at the title, 'Horned Mares.'
"It's something she wrote herself."
"Is that all, Princess?" I felt all tension in the situation decreasing. I took a few breathes to calm myself.
"Yes, would you like to ask me any questions before I leave?"
A million thoughts went through my mind. Something that I've always been curious about. What could there be? I know! I put a hoof to my mane, "Why do I have this?"
She frowned in confusion, "What? A mane?"
"No," I chuckled "well…why do I have a rainbow mane?"
She and I both looked at Dash, "You still haven't worked it out yet, have you?" Dash and I shook our heads, "Twix, when you came to Equestria and were still human, your body started absorbing genetics in Equestria."
I could tell from Dash's facial expression, she had no idea what Celestia was talking about, and to be honest…neither did I. She turned back to me.
"We still don't understand, Princess." I sat down, as did she and Dash.
"Think of yourself as a baby that hasn't been born yet," I nodded, "you're still absorbing foods and nutrients to keep you alive from your mother," I cringed but kept nodding, "this is the same case. You weren't born in Equestria, so your body…doesn't know what your physical appearance would be. In simple terms, you inherited those colours from Rainbow Dash. You spent much time with her before your transformation that you gained colours from her. Just like looking into a mirror."
"But," I pointed a hoof to my nose, "why the golden stripes?"
"Because everypony is unique, Mr Sunflower Twix."
If you don't know what "horned" is, Google it...I don't mean as in a 'unicorn' either, btw. ;)
