I suggest this partly as a joke and partly simply to share a thought that came to me; considering all male parties are dead, it could be conceivably be possible for MCs parents and Fionas parents to have partook in a foursome or swinging.
But you still haven't disproved that Riona's husband is not Cat's father
not necessarily, its already established that Tom was a sperm donor in Sophias case, we dont know if it was a "custom donation" or if there are "donations on file" at a bank. there could be other sibs out there.
gonna have to update the chart since this update added a new member to the MC family
I might be misremembering but If I recall Liz kind of insinuated that Katie's dad was a good for nothing shitbag, which would lead me to believe that she knows who the father is. I could be wrong, but I don't get the feeling from what we know so far that his dad was a shitty person, so I feel like that's an incredibly long shot.
Nana is still very much alive though...
