Yep, to me, Rick is the heart of the show....it began with him, and in a way, it’s always been about him. He isn’t perfect, but he’s been through a lot, and he’s done his best to keep everyone safe.
Is the preview the one where Carl is yelling “wake up?” I wonder if it’s because he’s in such awful shape after that beating he took. I hated seeing the governor get the best of him that way.
Wasn’t Rick shot in the leg, too? Maybe he gets an infection and Carl is yelling at Rick to “Wake Up” because he’s worried his dad might not make it.
In the comics, it’s because Rick falls ill and is dealing w/ the loss of Lori after the prison falls. Carl ends up taking care of him for a while.
