It needs a proper shake-up... something new and exciting to happen!

They need to find a bunker somewhere (possibly military) maybe a few main characters die in the confusion. Then the group find out that the military are (somehow) tracking all the zombie activity in South-Eastern USA. We learn about a few military-controlled areas in certain cities. One of the sites are conducting advanced experiments on the infected and we learn a little bit about what's happened.

Either that or Carl gets Carol pregnant.
