But not the entire horde followed her, right? And even so, they're down a flight of stairs or two?
Oh, because we've been fighting them throughout. I would've figured they'd be approaching by now.
Maybe it's just that my post isn't clear, but they aren't that close. A part of the horde would be close enough to be a threat, but the general bulk of them would still need time. I'm thinking there'd be hundreds, even a thousand of them in the main bulk, but maybe dozens up to a hundred was getting close. There will also be some zombies that would be way ahead, i.e the ones at the barricade. So yeah.
EDIT: Because already, it was mentioned that there were already zombies pushing at the barricade, and more of them are cornering Amy?
EDIT2: I'm getting long winded. But isn't the scenario right now about a horde pursuing the group?
