Speaking to E! Online about the new season, King explained that Lydia Adams will be paired with a female detective in future episodes.
"It's really cool - the dynamic with having the two women as partners," she said. "We're not Cagney and Lacey by any means, but two strong personalities together that detect two different ways."
However, King hinted that Lydia's former partner Russell (Tom Everett Scott) will be resentful about the changes.
"Some real interesting things are going to happen," she said. "Russell's just not happy with the situation, period, so obviously when he sees Lydia out with her new partner it's a little sting."
The new season of Southland begins tonight at 10/9c on TNT.
