I noticed something about Mel at the end of season 2.
Throughout season 1 her make up is purple eyeshadow
While she was kidnapped by the black rose obviously it came off.
When we see her put together again it is after her mother died and she is taking up the mantle.
We can see she still has her purple eyeshadow, however the red under her eyes matches her mother.
Even this photo here Mel is adorned and dressed like a general however she looks so small and childlike compared to how her mother looked there. She's taking up as little space we humanly possible. She's not imposing like her mother was she's struggling to fit into this role.
And someone like Mel who struggles with identity will first dress and look the part in an attempt to transition into this new role better.
So she dresses similarly to her mother, even changing a small detail as her make up to match what her mother was. However we still see little bits of Mel in her identity.
She's come to a point where she's realised in order to be a Medarda she does not have to be the exact same as her mother or elder brother. She can still be herself and be a Medarda. She's still not entirely sure who she is, but she's getting there.
I really hope they explore her journey in noxus as I'm so curious as to how the Noxians will react to their new general who is also a mage and how that will tie into the overall story.
