I agree that this is most likely an episode featuring Cindy as a child with possible introduction to Termaine.

Theory about Termaine from above comments. She and the Witch could be frienemies, meaning they could have a common goal/enemy/interest, but also not really trust the other and want to be the one on top which makes them rivals
