These two sisters live in the camp with Dale. We're not sure what Amy and Andrea get out of it, other than killed. They help with babysitting and other womanly chores. Amy's bitten during the zombie attack on the camp and Andrea puts a bullet in her head, not wanting her sister to return as a zombie. That's just about the nicest thing a sister can do.
(Editor's note to self: add this to Living Will and show to sister.)
Carol's a housewife who sold Tupperware until her husband shot himself and her daughter. Carol is completely useless. When zombies attack, she just sits there until Glenn saves her.
Dale lives in a camper with two sisters, Amy and Andrea. It's a platonic relationship. Dale just misses having a woman around to do the dishes (seriously).
For a little added conflict, and by conflict we mean "pointless bickering," there's judgmental Donna who thinks that Women's Rights are in danger (because of zombies) and that Dale is immoral for living with two women. Um, Donna, shouldn't women be allowed to live with whomever they want? Donna's married to Allen, an ex-shoe salesman whose defining feature is his plaid shirt. They have two kids.
While searching for Lori and Carl among the Real Zombies of Atlanta, Rick is rescued by Glenn, a baseball-cap-wearing pizza delivery boy who guides Rick to a camp of survivors outside the city. The survivors are all flat characters who serve as little more than background color (a black-and-white comic still needs background color) but there's a little bit of conflict at camp.
Glenn's definitely the most resourceful. He sneaks into the city often for toilet paper and other supplies. Around the campfire, he says, "I was swimming in debt and would've given anything to get out of it…" (581). Hey, who hasn't wished for a zombie apocalypse to avoid paying debt?
Jim's a mechanic who also gets bitten during the zombie attack, but he was an emotional zombie anyway, often just responding to people in as few words as possible. The reason Jim's so sad: his whole family was eaten in front of him. Yeah, that would damage a guy. When Jim is bitten, he wants to become a zombie in the hopes that he and his zombie family can live a happy zombie life somewhere together. He asks to be taken far away to die and reanimate in peace.
We hardly get to know Morgan and Duane. They're the first survivors Rick meets after waking from his coma, so they mostly serve to offer him exposition on the outbreak. "All media shut down. […] Those things are everywhere" (94). That type of thing. He also provides a little inspirational advice: "You just got keep going, you can't stop to think about it… or you'll go crazy" (108). Embroider that on a pillow when you're not fighting off zombies.
Morgan, like Rick, wants to protect his son, and even alludes to teaching Duane to shoot a gun, just as Rick teaches Carl later on. We're not sure where Little Duane's mom is. Even though Little Duane whacks Rick with a shovel (kid has some mean survival skills), Rick's grateful they take him in and feed him. He returns the favor by supplying them with guns and a car.
Fun fact: The author named Duane Jones in honor of the actor who played the protagonist in the original Night of the Living Dead movie.
