Judith is alive (and cranky), Tyreese is on diaper patrol, Darryl has a case of the Mondays, Carol is back, Glenn became an action hero, Meeka might be the sweetest little girl ever, and Lizzie is a FREAKING PSYCHOPATH!!
Take all of that and throw in a bus full of zombies, and three new characters and you've got one AMAZING episode!
Here. They can explan it better than I can....
Aim high. Run fast.
