If I was writing Morah episode, instead of her being human, I thought it would be interesting if she was mix with dragon blood. Imagine a hanyou mingling with a full dragon demon, which is uncommon. Their child would have been defective. Morah part will be called tears of a moon dragon because she's fighting herself. It will be difficult for her because no one is like her. She will have to find her way, and come to terms with both halves.
When she transforms to her dragon part, it's more painful for her, it physically burns her skin, that's why she's normally in her hanyou form or human. The mirror making her transform is so uncreative. If anything it should remind her of her true self and persona, everytime she looks at it, her dragon counterpart stares at her with an evil smirk.
