I'm kind of confused, on the Walking Dead Page it says that Vernon is dead? How do we know this? I've watched the Shel story in 400 days and saw the talk about Vernon, to me it sounds like they got the boat but then the group got split somehow? Maybe Vernon abandons them on the boat or something? If Vernon dies and the other Cancer Patients did take the boat then why would they boat to Macon or wherever? I'm confused.
