High school chemistry teacher Walt got into the drugs business in the first place because he wanted to take care of his wife and kids. Last night on 'Breaking Bad' (Sun., 10PM ET on AMC), however, his illegal activities put their lives in danger.
Gus has finally had enough of Walt and his brother in law Hank. He drags Walt out into the desert with a bag over his head and fires him. He also says he'll take care of the errant Hank: "You have failed. Now it's left to me to deal with him."
When Walt protests, Gus delivers this chilling threat: "If you try to interfere, this becomes a much simpler matter. I will kill your wife. I will kill your son. I will kill your infant daughter."
