Let’s be brutally honest and not biased. Claire or Ada?

Who do you think Leon is married to? I am 100% sure it is between the two and not anyone else. I’m leaning more towards Claire, but I want to hear your guys’ thoughts. Before you go and say “It’s an unknown character,” that is just bad writing, wastes all of the chemistry building Leon had, a cheap shortcut, and makes no sense for his character.
