This is the third episode of the fourth season of the Walking Dead. After the cliffhanger from the previous episode, we get even a better one this time around and one that is truly a shocker. That being said, this episode is mainly a character-driven episode as we see the changes people must do in order to survive. Some of the characters we met in the first two seasons, are just not the same characters they are here in season four.
In this episode, "Isolation," the survivors with the flu are being kept in quarantine including Glenn and Sacha. Herschel decides to risk his life to keep the people alive. Tyreese is angry over the murder and burning of his girlfriend, and he orders Rick and Carol to find the culprit. Daryl, Michonne, and Tyreese head away from the prison to gather medicinal supplies for the sick people, but there may be a problem.
Overall, this is a fantastic episode, even if it's a little slow at times. I felt like this episode could have done very well as a murder mystery, something along the lines of Sherlock Holmes. A solid episode with another excellent cliffhanger. I rate this episode 9/10.
