5. Carl and Rick's Relationship Will Be Tested Further
From what little fans have seen of the second half of season 4, it looks like Rick will be in a bit of a bad way from the wound he sustained at the hands of the Governor. Prior to his hand-to-hand encounter with the Governor, it's important to remember that he was wounded in the leg from a gunshot. This can only mean more tests for Carl as he has to step up and try to take care of his dad. What will Rick's state be like as a result of that bullet wound? After all, this world isn't exactly known for its hygiene and sanitation, so Rick could possibly be on the receiving end of a rather nasty infection. There's no denying that the relationship between Carl and Rick has been a constant push and pull. Carl is forced to grow up in a world where moral decisions are difficult to make during a zombie apocalypse while Rick is constantly battling with how much to expose his son to. This will be a reoccurring theme throughout the course of the show as Rick struggles to let go as a father and look at his son as a fighter and a man, rather than a helpless child.
