What are the chances your favorite pony was secretly a changeling all along?

Yeah, probably about one in one.

This story is a sequel to Celestia Takes an Acting Class

Chrysalis had finally managed to escape from her prison. Not an easy task, given how Celestia had kept trying to have them continue their lessons while she was imprisoned, but she'd done it. Now that she was free, although guards were still looking for her, she decided it would have been a good time to pay a visit to the therapist Black Fire had recommended to her.
