It’s the end of the world as we know it… or is it? That was the big question heading into the series finale of 911: Lone Star with an asteroid threatening the area with a potentially doomsday-level threat. 

As the series finale opens, Carlos makes his way to the 911 dispatch center which is preparing for the impact of the incoming asteroid and the overflow of calls likely to come through once the asterid makes impact. Moments before the asteroid strikes, T.K. calls Carlos but not to say goodbye but because he’s been talking with Judd about the adoption agency rejection to fuel them to keep fighting for Jonah. T.K. says he has the perfect plan and will tell him when he next seems him as they each say I love you before preparing for impact and getting under the trucks for safety. 

The asteroid  makes impact and immmeately cause chaos across the city. Cell service and the hardlines are down putting 911 dispatch in the dark in addition al everyone out in the city who needs help. 

Verizon Frontline crew comes in with an emergency response vehicle that helps restore coms and the 911 boards begin lighting up like a Christmas tree as calls come flooding in including one from a college student at the college when Wyatt overhears a nuclear alarm going off in the background and dispatches the 126 team to respond.

Back at the 126, the crew expects to hear alerts going off as they emerge from their safe spot, but it’s quiet so they prepare to clean up the degree. This is when a man wonders in asking for help after an accident. The man tells the team about calling 911 and getting voicemail, so Owen radios into 911 and learns that coms are out at the moment. 

Did Tommy die in the 911: Lone Star finale? 

When we last saw Tommy in the penultimate episode, it seemed like Tommy had passed away quietly in the comfort of her home as she received a visit from her late husband Charles and seemingly slipped away on the couch. Perhaps that is why it was such a pleasant surprise when Tommy came too after the asteroid struck. 

Still seeing Charles, Tommy informed him she needed to go out and help people in need. While he tries to assure her that she isn’t needed and should remain with him, Tommy tells him that she needs to go out to help to which he alludes that he’ll see her soon. She races out and makes it to the 126 just in time to join T.K. and Nancy in the ambulance as they prepare to head out to respond to the nuclear reactor call at the college.

When the 126 arrives at the scene of the call, Wyatt informs the group he's trying to get in charge with the doctor in charge at the college who will know where they can find the nuclear shutoff button. As they clear the area, Mateo finds the doctor passed out on the floor and the EMTs race into action. Unfortunately, his brain is swelling from his fall. The only option is to perform an emergency craniectomy in the field to relieve the pressure on his brain. 

Knowing that the doctor's life depends on the treatment and the best chance of finding the shutoff button is the doctor, Tommy puts her career on the line by performing the craniectomy with help from one of the team's drills. The risk pays off as the doctor comes to in time for the doctor to tell Owen about the location of the scram button needed to shut off the reactor; however, the toll of performing the procedure takes it out of Tommy and it's clear she's pushing herself too hard.

The 126 team race to the reactor to hit the shutoff but as they arrive, the cooling tank ruptures via an explosion that injures the full team, some more than others. 

With the meltdown imminent, Owen pushes through his injuries and tells dispatch to send help as he works to get to the shutdown in time. We hear the alarm counting down to 10 and it looks like Own won’t make it but he manages to get to it just in time. 

Mateo, Judd, Marjan, and Paul are all in bad shape, but Judd passionately encourages his 126 family not to give up. Fellow first responders arrive and quickly begin working on the group as Mateo musters up the strength to tell them to go check on their Captain. We see these first responders get to Owen, but he’s unconscious and things don’t look good at all with a hint that perhaps he did not have a pulse.

As we flash ahead five months, we learn that Tommy is in remission, and her rumors are gone. She’ll need some checkouts, but she defied the odds and has a clean bill of health. Judd stops by and is the first to hear the good news that she’s in full remission and about to return to her first shift back at the firehouse.

911: Lone Star series finale ending explained: Does Owen die?

When we first jump ahead five months, we see Carlos lying on his couch as his alarm goes off. T.K. comes out to wake him, and Jonah rushes in to help wake Carlos up! We learn their story has a happy ending for the pair and they were able to successfully become Jonah's guardian. Turns out T.K. chose to walk away from his job to become a stay-at-home parent and he seems to be loving the new life with no regrets at all. We learn that T.K. is about to go back to the firehouse for the first time and hints that something happened to Owen, but nothing concrete is revealed.

We next jump to the courtroom as Mateo’s case goes to trial with the government attempting to deport him for assaulting the police officer in their altercation. Mateo tells the judge he believes in the institution of America and that America has been his home country since he was a baby. Mateo says he’s dedicated his life as a firefighter to saving lives, including during the nuclear fallout, and that he’s earned his place at the table. He too makes a comment about if his captain was there, giving us fear something happened to Owen.

So what is going on at the firehouse? Well, it turns out the 126 is getting a new captain: Judd! We see Judd sworn in as the new captain of the 126 and T.K. comes to congratulate him as Judd comments about having big shoes to film. As the team talks we learn that the judge fast-tracked Mateo’s citizenship and we also learn that Marjan is pregnant! 

All signs pointed toward Owen having passed away on the nuclear call from the injuries he sustained when the cooling tank exploded, but then T.K. calls Owen up on the phone! We learn Owen accepted the Chief position in New York, thus why he wasn’t present in Austin, and he's starting back where he first began as a member of the NYFD.

And with that, the show comes to an end with a series ending that tied up many of the season's storylines while giving fans an ending which left the door open for fans to imagine the 126 continuing to save lives together in Austin.
