I really really hope that Stella and Dill only gets to meet their dad's birth family well into their late teens or older, should the family get wind of Gramble being a dad. I really don't want to think what those useless folks would do if they found out the little cutie pie has two small childern in his care.
I had this conversation with my mom. Her sister sucks, but she has a daughter my age. My mom was willing to get back in contact with her sister for the sake of my friendship with my cousin.
Except literally nothing is worth getting back in contact with that fucker.
Gramble might be the same! Will give anything for the happiness of his children, but his children are just so incredibly happy with what he already gives them.
