Just a random kind of headcanon that crossed my mind - Casey Novak and Dewey Wilkerson
I was watching Malcolm in the Middle and thinking about how some characters would be in their childhood, so came to the conclusion that Casey would be like Dewey but in a very big and loving family. She would be equally bullied by older brothers (it's impossible not to see her as the only girl among many boys) and, of course, this taught her to be tough, she would often fight for control of the TV to watch Star Trek/baseball games, learn to fight dirty and be somewhat vindictive, writing down thing after thing, to get her revenge when she grows up and you can bet she'll do it. It's easy to picture her using a bag full of toys to beat up her bully older brother, I absolutely love that scene.
Of course, wearing pajamas and overalls 24/7. Casey and Dewey would also share the cleverness, courage, creativity and childlike manipulation required of a youngest child, plus a flair for sports and school, oh, and same love of animals. While he is a talented self-taught musician, she would be a great self-taught writer, which would lead her to the uni/school newspaper. And Dewey's weirdness? Well, she'd be like that too. She would have a group of friends like his, the strong personality making her their leader, of course her parents would be happy that she had some of them after years of being a lonely child at school.
And if she had a son, he'd definitely be a Dewey 2.0. He is so cute aw.
