That legally could not happen. To the state of Wisconsin, I am as related legally to Pat's estranged daughter as he is.
For any of you folks out there with kids, you should have your legal paperwork set up so that the state knows who you want to have your kids in case of the death of you and your partner.
Especially since the death of PCJ, I highly doubt that Pat's ex hasn't set up documentation for this. Even if she didn't, the daughter would either go to Ade's family or would remain with her stepfather (more likely).
I cannot reiterate enough, Pat has no legal relationship with his daughter nor is he allowed.
Yeah, this is the equivalent of his dumbass showing up to her college graduation uninvited, and presenting the keys to his rustang, expecting her to suddenly love him.
