You have a bad habit of trying to write for the series--filling in for the avoidance of reason. I'm talking about all characters--even more established groups like that seen at Woodbury, or an indivdual who was not living in primitive shambles such as Jenner at the CDC. No excuses. ...and exactly how did it all fall apart in mere days? Again, you cannot avoid the strong suggestion that society fell while Rick was in the hospital--and considering the peculiar habits of walkers, he would not have lasted for an extended amount of time. So, tell us how society (including communications) fell so quickly.
