Chrissy is Jonny's sister and Tom's love interest. When Tom first meets her, she's dating a former Bennie's rugby player, Davin. Tom is initially attracted to her because Chrissy is extremely beautiful; he ignores the fact that she's also genuinely interested in him and his emotional wellbeing. She checks and makes sure he's okay after Kylie gives her speech about what happened in Mumbilli, for example, and she also checks in on Tom's (nonexistent) granddad after she gives him a box of sheepskin things that are, unbeknownst to her, actually for Fin. Chrissy and Tom finally connect when she shares that her father died a few years ago after a massive stroke. They talk about how difficult it was for her to visit him and how difficult Tom finds it to visit Fin in the hospital. Their physical relationship begins when Chrissy helps Tom escape after the rugby match with St. John's, and they finally have sex for the first time at the end of the novel. Tom credits Chrissy with helping him rediscover himself after the accident and reframe his experiences in terms of their relationship milestones, not in terms of negative and accident-related instances.
