[The false Celestia continues to change size. Eventually, it will make it to double her height. Other than that the details will stay almost exactly the same as she, except for the horn will curve into--of course--a sharp question mark.]

[He smiles tightly. The shadow Celestia throws back her head, and he does as she wished. He admits it.]

I wasn't completely corrupt, not in this way. It was still enough for me to feel regret. To feel alone, in fact, and you were the first being that I could stand the company of for even a few minutes in this place. [Or any place, really.]

[He leans on his cane, though it looks rather strange--it's more the size of a scepter than any sort of walking stick.]

You aren't worth it, Princess. A few polite words sent my way would never have been enough to eradicate that weakness.

[And with that the shadow charges forward, swinging its horn downward at its original like an axe.]
