Maybe its just bc Abigail grew up with Pierre, so maybe there was and influence, and its a small town and its not like she went to a big school or lived in Zuzu city and had hundreds, maybe thousands of people influencing her everyday. And I don't know the Wi-fi connection in Pelican Town, so we can't rule out social media as an influence just yet...
Pierre raised her. He housed her, worked to support the household, argued with her, imposed expectations on her, disappointed her, and helped create the personality against which she defines herself. Even their conflict is evidence of intimacy. They know precisely how to aggravate one another because they are family.
I wonder if Rasmodius has done a single thing that can be considered remotely fatherly to Abigail?
Like, I get it. It's just a harmless theory, but you can't help but ask yourself if it's even really all that funny. Something like Joseph from King of the Hill works because it's better thought out as a joke, whereas in here it just feels like a bunch of red herring one-liners would fuel a grand conspiracy without really addressing how underwritten it all is.
