Because Patrick and Susan are siblings. Whether people are for or against incest there should probably be optional genetic screening mandatory for siblings to look for risk factors. Sometimes people are unaware they are related yup that's a thing. And this is not limited to people directly related to one another. Maybe that even becomes a sub-category or match-making function on dating sites some day. I can only suggest this because I am out of the dating scene. I will not submit my DNA to anyone. Already had enough fun fighting the military on that one.
