Another amazing Netflix show. I got a question about Ruth, though:
Why did she have a change of heart about saving Marty from Russ/Boyd? Was it because she was getting close to the Byrds or was she doing it to learn more from him? If it's the latter, it doesn't seem like much motivation to kill off her uncles.
He trusted her/brought her into it. She also got the point that if they fucked Marty, that the cartel would come in and look for their missing money and would likely hunt them down, even if they split.
