ET got a first look at Eddie Cibrian on the set of Rosewood, where we found out what fans can expect from his mysterious character, Captain Ryan Slade.
"You don't know what you're going to get with him," Cibrian tells ET. "He can be hot or cold in a second."
The 43-year-old actor replaces Brian Austin Green, who left the show while shooting the first episode of season two.
As the newest member of the East Miami Police, Capt. Slade will both challenge and complicate the already messy situation between Rosewood (Morris Chestnut) and Villa (Jaina Lee Ortiz), and his methods are dicey at best.
"When he does interrogations, they are out there," Cibrian says.
According to Cibrian, Slade's murky past will also be explored this season.
"He grew up in a boys' home and then you find out that he was seeing a prostitute, but not for the reasons you think," Cibrian reveals.
While their onscreen relationship might be testy at times, Chestnut and Cibrian are friends in real life after working on a couple titles together, including The Best Man Holiday. Their chemistry is part of what's pushing the show over the edge this season.
"Season two is going to be bigger, it's going to be bolder, better, sexier, grittier," Chestnut says. "There is a whole lot of 'er's in there."
Rosewood returns to Fox on Sept. 22 at 8 p.m. ET/PT.
