‘9-1-1: Lone Star’: Ronen Rubinstein & Rafael Silva Break Down Tarlos’ Relationship Timeline

To say that T.K. (Ronen Rubinstein) and Carlos’ (Rafael Silva) journey to a happily ever after — which Rubinstein says the series finale “truly” gave them — wasn’t easy on 9-1-1: Lone Star would be an understatement. But aren’t the most worthwhile journeys the hardest?

The firefighter-turned-paramedic and the police officer met when the former moved to Austin with his father, Owen (Rob Lowe), after a heartbreaking end to a relationship and an overdose. And while T.K. tried to keep things casual, it quickly became apparent these two could — and would — have something special. What followed was a journey of ups and downs, leading ultimately to a happy ending, with the two becoming a family, having adopted T.K.’s half-brother Jonah.
