Something had told her to expect this. She knows what it's for. But she tilts her head slightly, as if befuddled at the request.

"The keys? What for?"

She knows this is going to come down to her holding out on giving the keys up, and the fact that she feels so strongly about this doesn't seem to make sense—why shouldn't they go out and save other survivors? Why shouldn't they gather up the people in the library and save them too? But she does feel strongly, for some reason, that the van should remain here and that no one should go out in the fog.
