Dominique Riley

Detective Dominique Riley, is a private investigator and now placed to work alongside the Hawaii Five-0 Task Force. Dominique is the daughter of Anthony Riley and Maria Riley (neé Reyes) and sister of Austin Riley and Nicole Riley.

Background
Dominique was born in London, England to stock-trader Anthony Riley and his wife Maria Riley. It is revealed that Dominique's parents met in Italy whilst her father was on business and her mother was travelling Europe. The pair married in what Dominique described as a "whirlwind" due to her mother being pregnant with her older brother, Austin.

Growing up her mother worked between jobs in order to keep a roof over the family's head, eventually settling in Florida and opening up a coffee shop. Her father was not always present during her childhood due to travelling frequently for his job. Her cousin, Sofia Reyes, believes this is the reason Dominique is so guarded and finds it hard to trust people. Despite not being around, Dominique insists her parents are still 'blissfully in love' and her mother was happy to raise the children whilst her husband was away. She reveals to Steve that her father 'never missed a single Christmas'.

Personal Life
Dominique has had few relationships, but most notably her relationship with Justin Odesky. The pair met in high school and were described by Dominique's mother as 'childhood sweethearts'. Dominique ended their relationship when she moved away to college, subsequently leaving Justin heartbroken. The pair united once Dominique finished college but their happiness was cut short once again, when Dominique moved to Los Angeles to work as a Private Investigator. It is thought that Justin never got over his loss of Dominique after several attempts to win her back, however he seeks comfort in the arms of Dominique's younger and cunning sister, Nicole. Justin later tells Dominique that her prioritising of her career over him led to the demise of their relationship.

Dominique meets Steve McGarrett when she flies to Hawaii to assist a client who is also seeking help from the Five O task force. The pair initially clash although it is clear there is a chemistry between them. Steve later asks for Dominique's number and the pair begin dating.
