twilight and celestia have long dropped calling each other by their titles. twilight freely calls her celestia, and celestia is overjoyed about it.
but in her royal chambers, from under the sun goddess, twilight can't help but call for help from the Princess, calling her nothing but princess celestia. celestia recognizes this state, and only soothes her in it, preening her wings a bit and making calming motions with her magic on her lover's coat as her hooves are quite occupied at the moment. twilight might be a full grown mare, but her Faithful Student needs her just as much as before.
