The return of the The Walking Dead started with a bang . . . and a few zombies. Picking up from the mid-season finale, Merle and Daryl were forced into a fight to the death. Just before things got really ugly, Rick and the group caused chaos and escaped with both brothers. This seemed to put the governor into a hate-filled, Terminator-like state.
They regrouped on the road, with heated discussions leading to Daryl and Merle heading off on their own, despite Rick's pleading for Daryl to stay. That really pissed him off, and he promised Michonne that they would patch her up and send her on her way. Later down the road, Glen judged Rick for not killing Merle.
Back in Woodbury, things deteriorated quickly. The residents were attempting to escape and were held back at gunpoint. Just as a riot was about to break out, walkers were discovered and attacked one unlucky guy. He survived, but sustained several bites. That's when the governor made his first appearance since Merle's escape and put hm out of his misery. He later announced to Andrea, "We're at war."
And finally, Rick decided what to do with the new arrivals that Carl found. After encouragement from Herschel, he seemed about to let them stay. That's when he began hallucinating. He looked up and saw Lori standing over him. Then he started yelling almost incoherently, which gave the new group the answer they needed. So, for now, anyway, they were turned away. And Rick is losing his mind.
