Abigail "Abby" Jones, an Iraq War veteran and con artist, serves as Laurent Thierry's second-in-command. Born in Iraq, she trained in ballet from childhood, winning a gold medal in a competition. Her life shattered when a Baghdad air raid during the U.S. invasion killed her parents as they left the venue. This tragedy drove her into an extremist militant group as a child soldier. During an assault on a military bunker, her comrades perished; she narrowly survived, stunned by a grenade detonation. These experiences left her with severe post-traumatic stress disorder and persistent suicidal tendencies. She carries her dented ballet medal as her sole memento of her parents.

Initially emotionally closed off, Abigail presents a cold, blunt, and taciturn demeanor, rarely sharing personal feelings. Unresolved trauma frequently leads her into dangerous situations. Her personality blends strategic ruthlessness in cons with underlying compassion, especially towards teammates. She possesses exceptional physical abilities, honed through ballet and combat, alongside strong acting skills used to manipulate targets through her appearance. Though self-identifying as a lone wolf, she gradually develops loyalty to Laurent's crew.

Her con artistry spans major operations. In Los Angeles, she infiltrated Eddie Cassano's entourage as a mysterious woman to sell a fake drug. During the Singapore Sky case, posing as a pilot in a rigged air race, PTSD flashbacks mid-flight nearly caused crashes until interrupted by Makoto Edamura. This case marked the start of her emotional opening, particularly toward Makoto, whom she warned about her complex nature. Her development continued through subsequent cons: a London art fraud and a Tokyo human trafficking operation targeting the Suzaku syndicate. In Tokyo, her participation in a staged shooting to maintain cover intensified Makoto's confrontation with his father.

Key relationships define her arc. With Laurent, she maintains a partnership built on mutual respect but initial distrust, frequently criticizing his methods while relying on his guidance. Her bond with Makoto evolves from skepticism to deep trust, demonstrated through protective actions and a unique farewell gesture symbolizing unspoken faith. Her dynamic with Cynthia Moore involves professional collaboration during cons. By the series' conclusion, she remains in intermittent contact with Makoto, indicating sustained camaraderie.

Physically, Abigail has brown skin, purple eyes, and initially short brown hair later grown out. Her typical attire is a yellow T-shirt, white low-rise shorts, a red cap, and white sneakers, though this changes during undercover operations. Design inspirations cite influences from specific actors.
