A community has risen inside the prison
With more people come more responsibilities. The council (made up of Rick, Sasha, Daryl, Hershel and Carol) now govern this newly formed community and doles out responsibilities. For those looking to earn their keep, they're tasked with a number of jobs such as tending the garden, feeding the livestock, maintaining the shelters, clearing the gates of any walkers.
As more is detailed about this council, we wonder what cracks in the overall foundation will be exposed as straits become more dire?
