When fans of AMC's hit The Walking Dead last left Rick Grimes and much of his crew, they had been corralled in a railroad car at Terminus, a safe haven that turned out to be anything but.

In the opening minutes of Sunday night's premiere, "No Sanctuary," Rick, Darryl, Bob, Glenn, and some others in the group prepared improvised weapons, intending to fight for their lives when the railroad doors opened, but the Terminus residents had things down to a science, tossing a flash bang grenade into the boxcar to disorient the prisoners.

What about Carol?  Carol went native, blending in with walkers to hatch an assault on Terminus, targeting a massive propane tank.

The Walking Dead returns next Sunday night, October 19, on AMC!
