This story is a sequel to Unrequited
Rainbow Dash has been practicing hard for her big performance, and wants to show her stuff off to Twilight, who in which has been distracted lately, thus getting Dash curious about what is going on. She then starts to look into what is happening, but she also finds something that she hopes not to be a possibility at all.
P.S. Please note that this storyline is happening a little during the original story from Unrequited, and is going to be a bit slower paced. It will also continue on from the end of the last story. Chapter one starts the night before Unrequited officially starts. Oh and, you will see what i meant by Alicorn like powers here soon enough.
