Grace has coily dark brown hair, brown skin and brown eyes. She wears glasses and an orange sweater.
Grace is a stereotypical shy nerd. In Chapter 6, it's discovered that she has a criminal record, and is believed to be unpredictable. Her unpredictability supposedly comes from her rocky relationship with her mother, Blaire Hall.
In the beginning, Grace feels neutral about Your Character. If you tell her you trust her to keep the tooth she found by the pool a secret until she is ready to tell group, she starts to like him/her. If you have a high enough relationship with Grace by Chapter 15, she will trust you with a letter that she wishes you give to her mother in case she doesn't make it home.
At first Aleister doesn't like her, but soon he does like her because of her kindness towards him. They both have romantic feelings to each other. In Chapter 14, if you choose to tell Grace to confess her feelings to Aleister, they share a kiss. And later when you go to Grace's room, he is there too. If Grace is left behind in Chapter 16, Aleister will express sadness towards her disappearance.
Blaire Hall is Grace's mother. As revealed in Rules of Engagement, the pair have a shaky relationship as Blaire constantly puts her work before Grace. Before Grace left for La Huerta, Blaire left her a message asking her to call her before she boarded her flight.
Craig dislikes Grace because of her nerdiness. When Grace suggests that The Celestial was a creepy place, Craig gets angry at Grace for "raining on my parade"
Zahra also dislikes Grace because of her nerdiness. Zahra enjoys teasing Grace about liking Aleister and being afraid of heights. You can choose to support Grace or tease her along with Zahra and Craig.
