Celestia had explained her plan to me, and I thought it was very clever. "The ponies of Canterlot thrive on intrigue and rumor. You wouldn't be afforded respect as an oddity, nor would you be instantly accepted if I set you loose. By keeping you close, but not discussing your position in my court, you are in a position where ponies have to assume that you are important. Also, by keeping you at my side with no extra guards, it communicates that you are safe. It means less anxiety for ponies that meet you in situations where you are alone, and allows you the acceptance you would need to live in Equestria as a happy member of society, for as long as you are with us."
