Jackie is a little girl Hazel Grace first encounters in the mall. She is described as having barretted braids, and appears in front of Hazel, asking her about her cannula. Her mother looks disapprovingly, but Hazel Grace says it's okay and lets the child try the cannula. Jackie says she thinks the tube is helping her breathe better, and Hazel politely takes it back. Jackie then thanks Hazel, and is next whisked away by her father.
After Jackie leaves, Hazel Grace resumes reading Midnight Dawns and compares Jackie to Kaitlyn, her other friend, and realizes how much she likes the little girl. She knows it will be depressing because of how all her other past friends talk to her because they will try to hide how awkward and self-conscious when in reality, it's very obvious they're trying to do that, "except for kids like Jackie who didn't know any better."
