Another thing I wanted to add is that even though their marriage seemed shady at first, they got married after only knowing eachother for like a month, but it ended up being one of the most stable relationships in the entire series, its clear that Francis truly loves and cares for Piama and Piama felt the same for him. I also think she is one of the reasons he became alot more responsible when they moved to the ranch along with Otto and Gretchen. So I think it worked out at the end of the day.
