Chloe Graves is Duke Jones' assistant or at least that's how the team meet her during "Nikki Heat". In fact, her real name is Greta Morgan, a former exotic dancer with a record, and now the honey in Duke and Stacey Collins' honeytrap. When Stacey is murdered and Duke drops off the grid, Greta goes into business for herself, but her involvement in the marital sting operation sees her arrested by Ryan and Esposito, and questioned by Beckett and "Nikki Heat" (Natalie Rhodes ).
