She debuts in the first episode of the second season and is portrayed by starring cast member Gina Torres. She is the child of divorced parents, which she did not take well and slashed the tires of her mother's first boyfriend's car.
In , she was working with the as a paramedic captain and she's sent on an emergency call with the , where we learn that she already knew Judd, about a woman who was yelling from the inside of her house. She starts treating her and when she asks Judd to help her on the gurney, the woman starts screaming at Judd to get out of the house. Later that year, she announces to Judd and Grace that she is pregnant and in , she gives birth to Isabella and Evie.
Her and Charles name Judd and Grace their babies' godparents. She's the one who trained Michelle Blake. She froze during her first emergency call because of all the pressure she feels. She gets angry at Charles after her first 24 hours shift because she hasn't seen their daughters for 24h.
Charles is not breathing, he has no pulse, no reaction to sternal rub, cool to the touch and rigor has started to set in. Tommy quickly realises that Charles is gone and she asks the dispatcher to tell the paramedics to not have their lights or sirens on because she doesn't want them to wake up her daughters. Tommy goes to their bedroom to change out of her uniform, and she tells the paramedics to take Charles' body to St Raymond's because she called ahead and a doctor, Mary Roberts, will do the postmortem.
Then she goes to sit on the couch, sitting there and zoning out for the rest of the night. The next morning, she starts to prepare breakfast for Evie and Isabella. When the two wake up, they immediately ask where Charles is. Tommy answers that he couldn't be there now so she's the one cooking breakfast for them. Evie asks about the car that she heard during the night in the driveway and if that was Charles leaving and Tommy lie to them by saying that it was him.
