Yeah, it doesn't seem likely at all, but the idea that there are even organizations like that out there is very interesting. I remember reading somewhere that Renner felt like there was some evidence to suggest she was pregnant. I can't remember the details, but that's what he said and so basically his underground railroad theory went something like this: Maura Murray got pregnant by her boyfriend, who mistreated her. She didn't want him to know that she was pregnant, because she thought he would be an abusive father. So instead of allowing that possibility to play out, she fled with the help of one of these organizations.
