Where the second season centered on the farm and the third and fourth seasons had the prison, Season 1 of The Walking Dead revolved around Atlanta. A wide-eyed and clean-shaven Rick Grimes galloped into the city on the back of a horse, full of hopes for the recovery of his family and dreams of a refugee center. As he discovered very quickly, Atlanta featured neither. It did, however, boast quite an ample supply of Walkers so indiscriminately ravenous that they are able to take down and rip into a rearing horse with little trouble. Were it not first for Glenn and then for a massive explosion, Rick's adventures in the world of the zombie apocalypse would have ended very early. "Do not enter the city," Rick later radios to Morgan. "It belongs to the dead now." Well, Atlanta may belong to the dead, but Season 5 will see somebody making a return. We don't see enough to say with any certainty whether or not the Atlanta scenes will be flashbacks to the early days of the outbreak or in present day for any characters, although the image of Daryl in his current warm-weather wardrobe as he scouts out a city block is a bit of a giveaway. Judging by the Walkers on that city block, it's not much of a gamble to say that he and anybody who might be with him would not have returned to the city of the dead without a very good reason. Considering that there have probably been far fewer deputies riding into the heart of the city on horseback in recent years, the congregated Walkers of Atlanta will be particularly formidable to any intruders.
