She’s not dead, but she might as well be. She doesn’t have anything, or anyone, to live for. No job, no friends, no hobbies.
But even she can’t say no to a friendly zombie lady. It’s ironic, but she seems to be making more friends after the zombie apocalypse, not before. The best part is, the zombie doesn’t seem to want to eat her. Maybe because she’s dead inside.
But finding a friend at the end of the world tends to make one feel human and alive. Probably not a good thing if your only friend has a ravenous appetite for the living.
