Helping the disciples as Charlotte is against the point of starting over! The Emperor was an exception, and she didn’t need gloomy boy to think she was Charlotte for long, so she better clear things up once the brainwashing is broken!
@Gotham2298 I'd imagine whatever she said at the start of this... her disciples are far more important to her than her own wish for starting over, if they're in such bad shape that they're letting some twat walk all over them like this. Her wanting to keep a low profile and hide from them was supposed to be "for their own good," so they could grow a bit and stop depending on her so much. But, instead this one pretty much self-destructed trying to find her at any cost.
