Day 2 of "The Walking Dead' week: The series will introduce new cast members in Season 2 as the gang we've come to know and fear for leaves the CDC and the heavily zombified city areas for the country. (That doesn't turn out to be as peaceful as it sounds.) Tune in to AMC at 8 p.m. Oct. 16 for the Season 2 premiere of "The Walking Dead." Curt Wagner, RedEye's Show Patrol
