The Walking Dead: 10 Crazy Theories For How It All Ends
4. Island Paradise
This idea is so simple it's almost stupid. Islands are small, and in turn, far easier to clear. If the group can thoroughly clean out a small island, they could live in absolute certainty that walkers can't reach them. A small society could be grown, a sustainable life could be built, a new world can begin. From there, the group could start to move onto land and repopulate, slowly working their way across the country.
It's the ultimate happy ending, but it sounds more like a failed experiment at some point between now and the very end of the show. After all, the grand finale is going to be a bloodbath, and how can that happen if the group are safe? Still, a happy ending could shock everyone.
