AMC's The Walking Dead Season 4 Episode 3 [WATCH NOW] [FULL RECAP] Watch The Walking Dead New Episode / The Walking Dead Season 4 Spoilers 

Episode 3 of season 4 of The Walking Dead just aired and just in case you missed it, you can check out the full episode down below this article.

Last night's episode was called "Isolation," which should have been called "Infected" because the "glorified cold" is spreading throughout the prison like wild fire.

Glenn and Sasha came down with cold and the virus can't be stopped. The virus itself isn't what kills you; it's the symptoms that come along with it. Daryl, Michonne, Bob, and Tyrese all head off to try and find antibiotics at the veterinary hospital.

Hershel helps keep the virus symptoms down by picking elderberries and going into the sick cell block and giving it those who have the virus, despite his daughter's wishes of him staying in quarantine.

As you probably guessed last week, Carol took matters into her own hands when it came to the virus and used deadly force to stop it's spreading by killing Karen and David. Her conscience is slowly catching up to her after Tyrese asks her to keep an eye on Sasha who is now severely ill.

Rick finally realizes that it was Carol who burned them alive. She later admits that she was the one behind the murders. Rick understands why she did what she did, but that doesn't mean she's in the clear. Tyrese is clearly in war mode after the deaths and he more than likely not accept Carol's logical, but heartless plan to stop the spread of the virus, after all she killed the woman he was growing to love.
