In the previews, they showed Maggie screaming at the raid-gear walker but in the episode, it didn't happen at all. I know its not essential or a big deal but the fear played very nice in that little scene and her prevailing over it made it seem more bad ass. But in the episode its just, gut! You're dead! Its also one of those things where if its constantly advertised and then you never see it, you're like wtf? What happened to that one part they kept showing lol.
