I suppose it is possible that Ozpin is playing a Dumbledore. He knows Cinder is present and is not taking action, preferring to monitor her actions to see if he can divine anything about her possible sponsors and their plans. It's a high-risk strategy but perhaps he's confident that he has everything vulnerable covered in some way so that Cinder can't cause any real long-term damage.

It will be interesting to see who has fooled whom!
