Not only do our favorite characters from AMC's "The Walking Dead" have to fend off walkers but there are rumors that Lizzie could be a threat as well. This isn't the first time this rumor has circulated. Earlier in Season 4, it was speculated that the little girl had something to do with the murders of David and Karen.

While the group was still at the prison, a flu-like illness started to make several people extremely sick. To keep the illness under control, the sick were quarantined in another area of the prison. In one of the episodes Tyreese stumbled across the burning dead bodies of Karen (his girlfriend) and David.

Carol confessed to the murders and was banished by Rick. However, viewers felt like Carol would never murder someone in cold-blood and wondered if she was covering for Lizzie. It's hard to think about a little girl brutally murdering anyone but Lizzie was displaying some questionable behavior. For instance, naming and talking to the walkers is not ok.

Anyway, in episode 10 viewers got another glimpse at Lizzie's unstable behavior when we saw her watching a bunch of rabbits holding a knife. The camera cuts away before we can actually see what she does to the animals but we're sure it wasn't pretty.

Then, in the same episode, Lizzie almost suffocates baby Judith. Granted the infant's hollering made the small group nervous and scared because it would definitely attract any walkers in the area but the look in Lizzie's eyes was definitely not worry. She knew exactly what she was doing. If it wasn't for Carol popping up, who knows what would have happened to Rick Grimes' daughter.

We'll have to keep watching to see what Lizzie's up to but there are even more disturbing rumors about the little girl. According to Moviepilot.com, her character seems like it's based off the comic book character Ben.

In the comics, Ben likes to torture and kill animals and eventually murders his twin brother Billy. Moviepilot speculates that Mika could be Lizzie's next victim.

Do you think Lizzie is going to be trouble for the group? Is she dangerous?
