9-1-1: Lone Star Adds Parker Young as Carlos’ New Partner in Final Season, EP Teases ‘Very Special Chemistry’

A familiar face is joining the 9-1-1: Lone Star family in its fifth and final season. Parker Young ( Enlisted , Suburgatory ) will recur as Campbell, a Texas Ranger assigned to work alongside Carlos, first appearing in the Sept. 23 premiere (Fox, 8/7c).

“When these two guys team up, there’s a very special chemistry,” showrunner Rashad Raisani tells TVLine. “They complement each other on cases and they’re going to become great friends. They’re going to go to some very interesting places as a partnership.”

Though they initially butt heads in a brotherly sort of way, “they are great together, and the stories they tell are some of the most explosive and dynamic that we’ve done,” Raisani continues. Heck, he even sees the potential for a spinoff with these two: “I have been desperately pushing for that,” he admits. “I think that this season is going to be a proof of concept.”

Of course, Campbell’s arrival is just one way Carlos and T.K.’s lives are going to be shaken up in Season 5. Per Fox’s official logline, “On his 30th birthday, T.K. gets a surprise visit from someone from his past that could change his and Carlos’ lives forever.” What’s more, “T.K. and Carlos’ marriage is put to the test when Carlos becomes obsessed with solving his father’s murder.”
