Tyler Kennedy "T.K." Strand (portrayed by Ronen Rubinstein) is the deuteragonist of FOX's 9-1-1: Lone Star, and is the son of the main character, Own Strand. Along with his father, he relocated from New York to Austin, Texas with his father, and debuts in the first episode of the first season. TK became a dual certified FD-medic at 20 years old, though he starts out as a firefighter, before eventually deciding to become a Paramedic instead. TK is level-headed, smart, kind, and comfortable in his homosexuality. He does the very best he can to support those in need whenever he can and cares for other people before himself. TK can be a bit impulsive at times with his friends and family, including to his own husband, Carlos Reyes, as he would risk everything if not his life to save anyone in need.
