Do you think Fitch would be a good father?
YES.
One of my personal headcanons is that Fitch wanted to be a father, but the reason he hates demons is because they had taken that opportunity from him.
I like imagining that despite his stoic demeanor he's very good with kids, he's patient and attentive and he honestly likes playing along with games. It's the only time bits and pieces of his more compassionate side really shows.
I like thinking he shows some of his fatherly qualities without realizing it. For example he's extremely protective of those he cares about, he pays attention to small details like how much sugar you like in your coffee or if you use sensitive skin detergent for your laundry, and he gives blunt but helpful advice to someone who needs it.
