'The Walking Dead' season 3 returns Sunday with new episode 'Suicide King'

“The Walking Dead” returns on AMC Sunday night, Feb. 10, as the much anticipated second half of season 3 continues. Rick and his crew have cultivated a skill for fighting the zombies or “walkers” as the group calls them, but the big threat when season 3 returns is the living, as suggested by the Huffington Post today.

The Governor from Woodbury is bound and determined to get the prison, but that’s not going to happen if Rick has anything to do with it. They spilled blood and lost people from his group when they secured the prison against zombies. This is something Rick said in the first half of season 3 of "The Walking Dead."

Andrea is someone viewers will keep their eye on when the season continues. Fans watched her go from insecure and suicidal to very independent and self assured woman. Unfortunately, falling for the Governor seems to have changed all that. She has blinders on when it comes to what kind of man he is and she’s become a bit dependent on the devious head of Woodbury.

Rick’s group of survivors are slowly losing their strong sense of humanity as they’ve made concessions along the way during a few incidents when it came to taking a human life. In the beginning this group would do almost anything to save a human life, whether the person posed a threat to them or not. This has changed, as has the world they're living in.

“The Walking Dead” characters are not at all hesitant to take a human life today if they pose a threat. Rick struggles with keeping his humanity in check in this new world, as do many of the others in the group.

Besides the big showdown between the Woodbury crew and the folks from the prison, what else should fans expect for the rest of season 3? Viewers already got a glimpse of what Rick is capable of after Lori was died. He massacred zombies and chopped them into pieces as a way of taking out his aggression. He also was on the brink of losing it when he was talking to his dead wife on the phone, or so he thought.

With a new baby in tow, Rick has two children to protect, although his son has grown up too fast due to the circumstances of this new world and he’s taking on the duties that should go to grown men. He’s seen too much and he’s done too much to ever go back to being a child once again.

Daryl Dixon, who has become a much loved and respected member of this group, will have his brother to contend with. Now that Merle has returned, will Daryl’s brotherly devotion kick back in or will he stick by the people who have shown him respect and who have cared about him for the past year? Merle’s done nothing but belittle his brother in every scene they had together during the first season.

The much anticipated “The Walking Dead” returns Sunday night at 9 p.m. EST. with the episode, “Suicide King.” The show begins with the aftermath of the attack on Woodbury. It is in a shambles and the Governor’s anger puts him in a retaliation mode. New visitors show up at the prison, which viewers got a glimpse of at the closing of the last episode. Who are they and will they become part of Rick's group?
