Yeah I don't see how the W is tied to wolves, just cause they start with a W. I thought it has something to do with the stamp the kid puts on people's hands. As for Alexandria and the walkers have Ws....don't know what it means.
That's crossed my mind a lil as well, like theres a tie in between the A'S and the W'S but they've been shifting scenes and lil things here and there about these wolves coming for them. Recall the part when Tyrese is trippin and the radio is saying that a group of ppl have been spotted cutting zombies in half and carving on their foreheads. Theres somebody coming though that's for sure and I think most of that town will not be ready. Hopefully we'll see morgan save the day.
