There was unequivocal fear and panic in those eyes, something that few had ever seen. My spells were holding her completely immobilized, and were also putting quite an effective damper on her own magic. She was a sitting duck and I was her stalking predator. This was a position she was hardly ever in.
 
“What are you?!” she breathed, the panic even seeping into her voice.
 
I furrowed my brow slightly. “Oh come now, Celestia” I replied, “I may have changed for the better, but I don’t look that much different, do I?”
 
She shook her head gently. “WhatWho are you?? And what have youWhere’s Luna?!”
 
Now my expression was anger. “You are a blind fool, Celestia! I suggest you convince yourself to believe what has happened, because it has happened and there is no undoing it. ‘Luna’ was a pony that I once was, long ago, but you can forget about her. She was me, and she has now become me.” I gave a smug grin of satisfaction and lowered my voice to a deep whisper.
 
“Hello, Tia.”
