Walking Dead Season 4 Spoilers: Holy crap. The Walking Dead stumbled from one horror territory into another last night when Lizzie, well, maybe we should have known, I mean, Lizzie Borden took an axe and see where that got her? The character of "Lizzie" commits the worst crime imaginable. 11-year-old Lizzie stabbed her little sister to death to convince her fellow Walking Dead travelers that she might come back to life,

Okay, I mean it about Walking Dead Spoilers, if you haven't seen the episode, stop reading. Seeing that little girl with blood on her hands last week on AMC's The Walking Dead delivered me into the realm of "Carrie" or "Psycho." Just when you think Carol (Melissa McBride) and Tyreese (Chad L. Coleman) find  nice place, it turns into an Amityville Horror, with the ghosts of Lizzie and her sister, Mika, and almost Rick's daughter, Judith.

Lizzie Samuels was introduced in Season 4 of AMC's The Walking Dead in the episode "30 Days Without An Accident". She is played by Brighton Sharbino.

Emily Kinney, who plays Beth Green - currently MIA with Daryl (Norman Reedus) on her trail - saw this all coming. Weeks ago, Kinney told AccessHollywood.com that little Lizzie might not quite be a fit babysitter. She said "Yeah... She's not necessarily the best (laughs). I don't know that Beth would approve if she knew how it was going with the baby, but... for me, acting the role of Beth, it's nice because it frees me up a little bit."

Melissa McBride, who plays Carol, told The Hollywood Reporter, she really had no choice. Lizzie was already a kind of Walking Dead. McBride said "No, I don't think there was really any other option. There's a lot of nature versus nurture going on in this episode to look at. As much as it broke Carol's heart to have to do this and to realize this had to be done. They were walking toward the flowers in that scene and Lizzie says, 'You're mad at me and I'm sorry.' You'd think she'd be sorry for stabbing her sister to death, but instead she's sorry for pointing gun at her, so she just doesn't get it."

McBride said there was no real way around it, "It was something that had to be done in that world and under those circumstances; Lizzie in that world seemed inevitable. It would be impossible for Tyreese and Carol to move forward with Judith, who doesn't have any experience of the world before the apocalypse. It was so devastating for Carol to have to do that. Moving forward, Tyreese forgave Carol after she confessed to killing Karen. She put her fate in his hands and gave him the choice of, 'Do you think that I'm worthy of living?' He forgave her and he understood. That brings the whole humanity back. Moving forward, it's a new beginning."

"The Walking Dead" has been taking a deep journey into character development in Season 4. Two weeks ago on The Walking Dead, Daryl (Norman Reedus) lost Beth. The episode ended with a car speeding off into the distance and Darryl finding her backpack in the dirt, leaving us with the sneaking suspicion that Beth was abducted. Lauren Cohan says we have reason to worry about Beth and Daryl (Norman Reedus) in an interview, saying "That's going to be a really good point of suspicion for a while; there's not going to be a quick resolve to that situation. It gets very scary. This whole situation that Daryl has found himself in gets really scary. We should be pretty worried about everyone."
