Rick and Tyreese clash over the deaths of Karen and David, whilst the disease infects more people.
This is a solid character focussed episode with a focus on morality, leadership and humanity post zombie apocalypse.
As a plot, it's character moments are the strongest points, with Carol, Rick, Tyreese and Herschel having the best material. The overall narrative is okay, but it generally moves quite slowly and it is very easy to predict it's final reveal, which lessens the impact when it happens.
Tyreese makes the observation that 'murder is okay in this place now' and there are a number of scenes that portray varying ethical perspectives of characters. Group survival is of utmost importance to one character, whilst others like Herschel value the needs and suffering of individuals over even their own life. All these depictions contrast each other well.
The scene involving Carl and Herschel in the woods is beautifully filmed and includes fantastic, non-violent zombie effects. The art design here is absolutely top drawer.
This season has used the zombie extras to great visual effect and this is evident in one scene filmed on the road. Some of it is not very plausible, but it is very cinematic nonetheless.
All performances are excellent, especially Chad Coleman, Melissa McBride, Andrew Lincoln, and Scott Wilson.
