I love the name Mia!<3 sounds like a name Will would choose for her.

When you said 'disruptive' and 'hide secrets' made me think of something...Like, maybe she would talk a little around her father at some point, maybe as a way to make him think she wants his attention? But I mean in a way like she wants to know how her father would react to that, even if small. And then to bigger yells of attention.🤔

I kind of imagine Mia as a girl who analyzes whoever is there in front of her and gives a critical judgment in her head first, finding imperfections and small signs that usually escape the eye of all people. And so she did to her father, but it's hard to analyze him fully. That's probably a secret she keeps by heart, because she'd go to the line of 'not everyone deserve to know every secrets you have.' , including her own father.

Mia means mine in some languages, so I thought it would be fitting that possessive dad Will would choose that name :).

She’d be a very smart girl, I agree. I believe Mia would be a tricky kid to deal with, due to Will’s inability to reinforce boundaries, and so she would not know how to draw a line at what’s her problem and what’s her dad’s problem.
