Great episode. So far it's the best of the season. The male/female storylines worked pretty good.
I loved the scene just after the flying wrench, when we can see the reflex of Shane in the broken glass. He looks like a zombie himself. And then there's a dead hand followed by the dead body taking the place of that reflex. This scene goes great with the ones when Shane watches the lone zombie in the field.
I just don't understand Lori! She believes there're specific rules to men (to go out and fight and keep everybody safe) and women (to cook, do tha laundry and stay at home)! Was she raised in the Middle East? Haven't she heard about the Zombie Apocalypse? Come on!
