Calenthe automatically knows. She 'sees' through illusions. He is also not trying to hide from her, since she knows about his condition. I meant subtle because he is wearing a large coat which makes his figure hard to make out easily, and because he will step behind the others to transform, hoping they will be focusing on Elizabeth in front of them. The perception to notice the transformation would also be to know enough to turn around and watch him. Once again, Calanthe sees all the way around her, so she knows automatically.<br/><br/>This brings to mind the fact that I never want to get Alexander in a fight against Calanthe. She has the perfect anti-mage build and would probably crush him, despite all the versatility his huge spell list gives him.
