UPDATE: With the big reveal in Season 4, Episode 5, "Internment" that The Governor (David Morrissey) has been creepin' outside the prison for an unspecified amount of time — maybe for a second, maybe for a while — it's seeming pretty likely that he did the deed, or at least had some help from inside. But hey, hopefully we'll find out the real answer soon.
EARLIER: We’re still in a state of shocked confusion about Carol (Melissa McBride) as killer/savior, but it doesn’t seem like her choices with Karen and David are connected to the rats at the fence. She isn’t trying to sabotage the prison, she wants to help the prison.
So who is/was feeding the walkers? Some people initially thought Carol was just covering for young Lizzie, who is a bit “messed up,” especially when it comes to her fascination with walkers. Maybe Lizzie was feeding her zombie buddy “Nick”? We saw someone holding a flashlight to feed walkers, and there was some debate about the height of the flashlight suggesting a taller culprit.
In another scene, we saw Sasha pointing out multiple rats sitting inside the fence area. That looked like someone was trying to tease the walkers into pushing the fence to get to the rats.
It’s possible Lizzie was trying to feed her buddies, but it’s also still possible that we have a different kind of rat in the prison — a spy, a saboteur. We’ve been expecting to hear The Governor (David Morrissey) has a spy (or more than one?) on the inside, and the rats at the fence would hint to someone possibly pushing our group out, or at least distracting them with chaos.
Who could be doing that? We’ll trot out our favorite suspect, Bob Stookey (Larry Gilliard Jr.), since he’s 1) a character who was close to The Governor in the comics and 2) a new guy at the prison who just showed up right when the trouble started happening. He was always our #1 suspect … until The Powers That Be started acknowledging that it’s fair to worry about Bob. The producers are spoiler-phobes of the worst kind, so would they concede that Bob could be untrustworthy if he were really working with The Governor? Bob may be too obvious a suspect.
What about Dr. S.? Poor Dr. S. is probably a decent guy just doing his job (which is now dying) and nothing else. But since we know nothing about him, and his name has come up a thousand times in the first three episodes, we have to wonder if there’s more to him than we thought. If he lives, we’ll be suspicious of him. He can’t win!
Who else? Since Carol is now being presented as someone willing to kill two people to save dozens, our minds are have to be open to other (nonsensical) possibilities. Is there a harmless, logical reason why someone would bring rats to the fence, beyond Lizzie wanting to befriend them?
Do you want to break out a rat theory? When do you think we’ll learn the truth about it, and will it make even a lick of sense?
