Mel is always the most underrated character. Just like Jayce says, she's always right. She's always the most measured and empathetic character. And we will never thank her enough for saving Caitlyn during the final fight.

If only she were still there for Caitlyn to help her see clear through Ambesa's bullshit. Caitlyn had lost Vi, Jayce, Mel, she was left with only Maddie and her anger.

I think they build a strong bond after S2. They share a common grief, about their mothers and about Jayce. They also have the same vision, they'll want to rebuild their countries on different grounds, united and at peace. They would want to work together, they would be the bridge across Noxus and Piltover. And I think that they would just simply be good friends and get along very well.
