If you were wondering what the survivors in The Walking Dead have been up to since we last saw them sitting anxiously around a campfire seven months ago, the wordless five-minute opening scene in "Seed," the Season 3 premiere, says it all. No longer inexperienced and insulated from danger, the survivors have become a well-oiled army of zombie killers and marksmen who efficiently scavenge and quietly secure premises in a matter of minutes. They've become good at this, but their nomadic lifestyle has them looking more haggard and hungrier than ever as they continue looking for a more permanent safe haven. Worse, time's running out to find a proper place where Lori can give birth to Rick (or Shane's) baby.
Enter the prison, whose relative proximity as it appeared in the closing shot of Season 2 made it seem like an imminent discovery, but was somehow overlooked all winter when the survivors were going in circles trying to find a way out of the immediate area.
