I was honestly incredibly bored by the episode. Lots of drama, so I'm sure it's setting up for good things.
What really pissed me off is when Rick was talking into the radio to that guy and his son and he references the guy at the CDC and says, "I met a man there. He told me something. He told me... Forget it, it's not important"
FUCK YES IT IS IMPORTANT, THAT'S THE BIGGEST SECRET OF THE SEASON! DON'T TEASE ME LIKE THAT!
