The

Beginnings and endings consume this week's Firewall & Iceberg Podcast, as we begin what should be 12 straight weeks of "Mad Men" episode discussion with the premiere, talk about the returns of "Game of Thrones" and "The Killing," look at the probable series finale of "The River" and the definite finale of "Luck." And I also take a moment to apologize to frequent podcast punching bag Dermot Mulroney.

The line-up: 

Dermott Mulroney on "New Girl" (00:01:25 - 00:06:55)
"The Killing" (00:07:00 - 00:21:15)
"Game of Thrones" (00:21:15 - 00:33:40)
Listener Mail - CBS Sunday Delays (00:33:45 - 00:39:10)
"The River" finale (00:39:20 - 00:51:10)
"Luck" finale (00:51:10 - 01:08:30)
"Mad Men" premiere (01:08:30 - 01:34:40)
