9-1-1: Lone Star is returning for a fourth season, but it looks like Captain Owen Strand is in for a bumpy ride. Taking to Instagram, the show's account has shared a number of new clips from the latest instalment, which includes a particularly "harrowing" storyline for the firefighter.
Talking about his character's arc in the video, Rob Lowe reflects: "This year he's in a great place and he's having a hard time with it. Things are too good, he realizes he needs to be – not in crisis – but he needs energy."

Meanwhile, a third commented: "Why do I feel like these unsavoury people Owen is messing with will mess up the wedding? I feel a grand, dramatic and crazy finale cultivating in the wedding."
The other storyline described in the clip was that of the highly-anticipated nuptials between fan favourites TK (played by Ronen Rubinstein) and Carlos (Rafael Silva), which follows their heartwarming engagement at the end of season three.

"It's been a long relationship and they have been through so much and it's not a regular relationship," Ronen told HELLO! in May.
"TK is ready -TK can't see himself with anyone other than Carlos, and like Owen said, the work they do [means] tomorrow is not guaranteed so [the proposal] is a way for him to say, 'I know what I want and who I want in my life.'"
"I had this epic monologue in bed, holding his face," shared Ronen. "It's a beautiful monologue and I am so proud of it."
