Before Jason's Death
Before the death of her son, Grace appears to be a loving and cheerful wife and mother. She first appears walking in the house with groceries for Jason's birthday party. While she is in the kitchen preparing lunch, she asks for Ethan's help with getting various jobs done.
Sometime between early May and late September of 2009, Grace, Ethan, and their sons are seen taking a trip to the mall. When they arrive, she asks Ethan to look after Jason while she takes Shaun to buy some shoes. When she comes back, she notices Jason is missing. She and Shaun wait behind while Ethan goes on a desperate search to find him.
Ethan finally meets up with Jason outside the mall. Jason starts to run across the street while a car is approaching and Ethan jumps and catches him to try and save him, but they both get hit by the car. This results in Jason dying and Ethan getting put into a coma. Grace and Shaun watch helplessly as Jason and Ethan lay in the road. Grace runs out to her son screaming his name while crying.
After Jason's Death
After the death of her son, Grace and Ethan have divorced (presumably sometime in April 2011, based on Ethan's statement in "Welcome, Norman" that they have been separated for six months). They both share custody of Shaun, with Ethan seeing him throughout the week while Grace sees him on the weekends. One day after school, Ethan and Shaun go to the park. Ethan experiences a blackout and discovers Shaun is missing afterwards. Grace is later seen at the police station with her ex-husband filing a missing persons report. The detectives tell Ethan that they will try their best to find Shaun. Ethan then meets up with Grace in the lobby, and she asks Ethan if the detectives think Shaun was taken by the Origami Killer. He informs her that it may be a possibility, but it is still too early to say. Grace then shows some aggression toward Ethan. She seems to have fostered some resentment over the events of the last two years, blaming Ethan for Jason's death and now blaming him for losing Shaun, though she regrets this seconds later. The scene ends with her sobbing, stating that she deeply misses him.
Later in the game, there is another scene with Grace in the police station talking to Carter Blake about Ethan. She tells Blake that Ethan came home one night talking about drowning bodies and rainwater, which is associated with the Origami Killer. She then begs the police to find her son.
