A&E is showing a series called Bates Motel, which could be subtitled "How Norman Got That Way". He's 17 and the mother (Vera Farmiga) is very much alive. It shows on Monday nights, but since it's A&E, there are repeats scattered through the week.
AMC changed its corporate mind and renewed The Killing, which comes with a promise that this time the mystery will be solved by the end of the season. It's scheduled to start in a couple of months.
