|“|| I don't believe it... Harry, it's a baby... Cheryl. We'll call her Cheryl.
According to the novelization of the first game, Harry met Jodie at the beginning of his sophomore year of high school. He took the opportunity to ask her out after she broke up with her previous boyfriend. Jodie became Harry's priority as they fell in love. They were wed at a church soon afterward, and their nine years together are described as a "never-ending honeymoon".
When her husband was twenty-five, they found an abandoned baby on the side of the highway. With Harry's agreement, they adopted the baby, to which Jodie gave the name of Cheryl. It is revealed at a point in Silent Hill that Harry and his wife desired to have a child during their marriage, but were unable to conceive due to Jodie's illness.
Silent Hill suggests she died from her said disease. The game's manual confirms this.
The novel contradicts this by stating that while she was driving home from work, a car chase occurred in which a criminal crashed into her while in full speed, killing her. 
The guides are known for being inaccurate, and the novel, which is official, presents a different story, thus it is possible to be the latter. In either case, her death left Harry in deep grief while Cheryl was too young to understand what had happened.
In the intro FMV of the game, Jodie is seen finding Cheryl with Harry by her side. From her appearance in the introductory sequence, she has dark brown hair and dark eyes. She wears a long dress covered in a pink floral pattern (possibly cherry-blossoms), and a shawl around her neck. She is mentioned a few times throughout the game, first when Michael Kaufmann asks if she is with Harry, and Harry states that she died four years ago.
In the good ending, a radio transmission appears in which Jodie and her husband are heard finding Cheryl on the side of the highway.
- Jodie's name is mentioned only in the novelization of the game. In the game and its guidebooks, her name is never revealed. 
- In Silent Hill 3, Heather states: "But I do have just a trace of one more memory left. I haven't forgotten my sweet and gentle mother." It is unknown whether Heather was thinking of her mother as Cheryl or her mother as Alessa. It is most likely that she was remembering Jodie, as she seems to be in a nostalgic mood at the time when she is thanking her father. However, it is still possible to be the latter because Heather also states: "Mo... Dahlia used me to summon God" in Alessa's sickroom, and Heather is known for using sarcasm.
- Harry's apartment contains a hand-made art-piece of Mrs. Mason, holding hands with his two adopted daughters, which is presumably a dedication to his lost wife and child, with the addition of Heather.
- Many fans have speculated the possibility of Jodie having an Asian (Japanese) background due to the cherry-blossoms on her dress, her dark hair and eyes, and the various Asian references throughout the Silent Hill games.
- Heather has also spoken a bit of the Japanese language  and owns Japanese-inspired clothing (i.e. Golden Rooster, Royal Flush, Onsen, Transience, Killer Rabbit, God of Thunder, Princess Heart). Upon examining Japanese artwork of a mountain in the Gallery of Fine Arts, Heather compliments it as being relaxing and calm. In the same gallery, Heather also obtains a katana. If Jodie Mason is truly Japanese, it is possible that Cheryl had learned some Japanese from her mother when she was still alive, which could explain Heather's interest in Japanese culture.
- Although Jodie's voice actress is uncredited, she sounds exactly like Jennifer Woodward, who portrayed Lisa Garland in Silent Hill: Origins.
