THE WALKING DEAD
AMC, 9:00 p.m. ET
Last week’s season premiere brought us seaside, to a training exercise somewhere between medieval tactics and a blood-spatter videogame. The zombies being dispatched weren’t exactly frightening – but the scares will follow, in the future and in flashback. Tonight, we go back in time, and in the Walking Dead narrative, to learn the origins of both Alpha and Beta.
