The fans' long wait for The Walking Dead is almost over, with "Seed" starting the new season Sunday, October 14 at 9 PM ET on AMC. When we last saw Rick (Andrew Lincoln) and his dwindling group of survivors, they were forced to leave Herschel's farm in search of a new home. Today, AMC has released the first clip from the Season 3 premiere, which is obviously before they discover the prison. It also seems that Carl (Chandler Riggs) has grown up some, as he stands guard while the adults hash out their plans in this scene.
