I don't remember all the details of season 3 so why Jimmy suddenly "switched" after Howard says its his fault that Chuck died is a mystery to me. Is he relieved that nobody thinks its his fault? Was it his fault, I honestly don't remember - I remember Chuck basically knocking over the lamps to start the fire and I vaguely remember Jimmy visiting before but not what they talked about.
The Madrigal stuff is kinda weird, like Gus Fring doesn't own that giant ass company, right? Its some German conglomerate where Lydia works and Los Pollos is owned by it I think so Gus must be a VP or something, and they of course get their meth precursor chemicals through the company and I remember they shipped meth to eastern europe through the company I think but I don't really understand if the big wigs know they sell meth or if its something Gus just setup as a shell inside a big company. Guess we'll find out this season.
