- "My dad said he kicked your ass once."
- ―Samantha to Dominic Toretto
When Hobbs is hospitalized for injuries sustained in his fight with Deckard Shaw, Samantha is brought to the hospital to see him. She presumably remains with him until morning. She meets Dominic Toretto, who visited the hospital after he was contacted by Elena Neves. When her father brings up sponge baths, she protests the very mention.
Hobbs introduces Samantha to a very confused Dominic, who was unaware that Hobbs had familial connections. Not intimidated by Dominic, Samantha boasts Hobbs beat Dominic in a fight. Dominic assures her that Hobbs's recollection is muddled by the painkillers he's likely on. Samantha challengingly dismisses that as she is then escorted from the hospital room by Elena.
Later, when Dominic and his crew return to Los Angeles, one of the radio towers in the city is destroyed by Mose Jakande. Samantha takes notice of her father, who mentions Dominic by name and breaks the cast on his arm. Once he's dressed and armed, Samantha gives her father a fist bump for the road.
The Fate of the Furious
In The Fate of the Furious, Samantha is introduced with her soccer team. They face off the other team with a New Zealand haka before starting the game. According to Mr. Nobody, she is mentioned that as staying with her paternal aunt until further notice. After Cipher's escape, she was seen in the new apartment, Hobbs decides to retire from his job so he can spend more time with his daughter.
Hobbs & Shaw
Two years later, Samantha is having breakfast with her father at a diner where she explains that for her social studies class she has to make a family tree, although the tree only consists of herself and her father as she has no knowledge of any other family members, including her mother. She then meets Agent Victor Locke of the CIA, who reveals sensitive information about The Snowflake and rogue MI6 agent Hattie Shaw to her, with Samantha finding Hattie pretty.
While holding Hattie in custody, Samantha speaks to her father over the phone, and does so again shortly after Hobbs briefly becomes a fugitive, having become painted as a murdered due to Eteon's ownership over several media outlets. For her safety, Samantha is remanded to her paternal aunt's custody. After the Battle of Samoa, she is brought to Samoa to meet her paternal family for the first time, especially her grandmother.
