The music is pulsing. Woodbury is attacking. The Governor is at the gates, again. In this sneak peek of The Walking Dead Season 3, Episode 16, "Welcome to the Tombs,” aka the season finale, we see The Governor’s group looking like some real warriors. They mean business, even as this other sneak peek shows the prison group looking like they are packing up to leave. So did they vote to leave but as they are trying to get out, they are attacked? That’s cold, man.
