I smiled when I saw Celestia walk into the room but that smile turned into worry as I noticed she walked in with a frown on her face. "Um... Celestia..."
"it is time to come clean with what has been happening to you Derpy... and I greatly regret not telling you when we first determined what was happening," she said in a saddened tone as she used her magic and pointed her horn towards the doorway as I felt weird when she used magic in my presence.
"am... I going to die princess?" I then asked her in a sad tone as that was the only thing that she was going to tell me. Her head quickly snapped over to me as her eyes widened in surprise.
"no no no no!" she quickly told me as she walked over to the bed. "its something... much better than that. Quite a few would call it an honor to have happened to them... if we knew what was happening at first." she used her magic again as I felt funny as she brought a chair over which she sat down in. "it scared us at first because we thought it was something bad... what do you know about Alicorns Derpy?"
"I know that they are highly respected and that you, Princess Luna, and Princess Cadance are the last of the alicorns," I told her in a matter of fact tone as she smiled.
"you are correct about the three of us but let me tell you a small tidbit about the three of us. My sister and I are natural alicorns while Cadance... is a created alicorn." I blinked my eyes a few times as I processed what she told me.
"created... alicorn?" I asked in confusion. I didn't even know you could create an alicorn. She nodded in response as she took a deep breath.
"a created alicorn is made when either my sister or I set up a task for a specific pony when they have reached their limit in potential. It is very rare that a pony ever reaches their limit with Cadance being one of two that had in all our immortal lives."
"if Cadance was one of two what happened to the second alicorn?" I asked interrupting her explanation.
"nopony knows. She disappeared soon after she was turned into an Alicorn... or so what my father said before his own disappearance. Now onto what I was saying Cadence was turned into an alicorn when she reached her limit in creating love. She could only influence slightly with a small amount of love inside of couples but when she ascended... she could turn fighting couples into loving ones... which helped improve Equestria greatly and improved its standing as the country of peace." she said with a smile.
"so I'm guessing that natural alicorns are those born as an alicorn?" she nodded with a small amount of pride now in her eyes as I looked at her still confused as to why she was telling me this. "so what does this have to do with me?"
"the reason this has to do with you Derpy is that you are special in a way somehow..." she then started before she trailed off and we both remained silent for a few minutes.
"Celestia... I don't see how this pertains to me at all. You just told me about natural and created alicorns but I don't see what... this has to do...with the bump... on my... head..." my eyes widened as I finally realized what was happening as she gained a saddened look on her face as she stared into my shocked eyes. "you can't mean..." she proceeded to give me a slow nod.
"yes Derpy... that isn't just a bump on your head... its the making of a horn sped up over the course of days..." I fell back against the back of the bed as I processed what she told me. I didn't get clumsy at all and get a bad bump on my head... something happened and I was now growing a horn for no apparent reason at all. "we don't know how it happened but it started soon after we... had sex." I could notice her blushing out of the corner of my eyes. "only Doctor Surge and I knew what was happening to you and even then there was so many other possibilities about what could happen to you." I remained silent as I continued to process the information that she was telling me. "there was a possibility of you growing a horn when we saw that the magic inside of you was fixing your body and adding new things to it. Much like what my sister and I's magic does when we are injured in any way but we decided to see how things went and when the doctor saw you were growing a horn... I was shocked... yet filled with glee knowing that you would be by my side for the rest of our lives."
silence once again reigned inside of the room as she started to get more and more worried and I could tell from her eyes before eventually she just looked away as a sad look came onto her face. "can I at least ask one question, Celestia?" I asked turning to look at her as she turned to look me in the eyes... well eye but that's not the point at the moment. Soon I had a smile on my face as her eyes quickly turned into confusion. "does this mean I can use magic now?" she gained a smile on her own face before we both just turned into fits of giggles.
