How about a massive walker herd finally pushing down the fences?
Rick and Carl bond as father and son over a round of zombie killing as the undead finally work their way in through the fences. Gone are the days of asking "how was school" while shooting baskets in the driveway. Now it's "glad to see you're still alive" while stabbing wriggling zombies in the head!
Meanwhile, sweet little Lizzie got even creepier with her "here kitty, kitty" approach to one of the flu victims resulting in nearly getting eaten...... and when the melee was over, she casually runs her boot through bloody ooze on the floor as she talks with Herschel... much like doodling on a notepad. Something is up with that kid.
Rick told Maggie and Herschel about Carol, but Daryl has yet to find out, Glenn almost died, and as the episode ended, just outside the prison walls we see....
Check out this recap from those involved:
Aim high. Run fast.
