Tully and Kate. Kate and Tully. If you spent ten hours glued to your couch watching the first season of the Netflix hit, those names are basically etched into your brain. It's a show about friendship, sure, but it's also a messy, decades-spanning puzzle that refuses to play nice with your emotions.
Most people went into Firefly Lane season 1 expecting a cozy Gilmore Girls knockoff. What they got was a non-linear gut punch. It’s a story that bounces between the 1970s, the 1980s, and 2003, dragging you through the bell-bottoms of suburban Washington and the high-octane shoulder pads of a Seattle newsroom.
Honestly? It works. It works because it captures that specific, agonizing, wonderful reality of a lifelong female friendship. It’s the kind of bond where you can’t live with them, but you’d literally die without them. And that cliffhanger? People are still talking about it years later for a reason.
The Three Timelines of Firefly Lane Season 1
Let’s talk about the structure. It’s chaotic. It’s deliberate.
In the 70s, we meet "Tall and Lanky" and "The Cloud." Tully Hart (Katherine Heigl) is the girl everyone wants to be, living a life that’s actually a total wreck behind the scenes. Her mom, Cloud, is—to put it mildly—unreliable. Then you have Kate Mularkey (Sarah Chalke). She’s the girl nobody notices, hiding behind oversized glasses and a supportive, slightly suffocating family.
By the 80s, the dynamic shifts. They’re working at KPOC in Seattle. Tully is the rising star, the one with the microphone and the ambition that could swallow the city whole. Kate is the producer, the backbone, the one trying to figure out if she wants the career or the guy. Or both. It’s classic 80s office politics mixed with a love triangle involving Johnny Ryan (Ben Lawson) that stays complicated for decades.
Then comes 2003. This is the "present" day for Firefly Lane season 1. Tully is a global superstar with a talk show, and Kate is navigating a divorce and a teenage daughter who clearly prefers her "Auntie Tully."
Why the non-linear storytelling matters
Some critics hated the jumping around. They found it confusing. But if you’ve ever sat down with an old friend, you know that’s exactly how memories work. You’re talking about your divorce in 2003, and suddenly a smell or a song triggers a memory of a party in 1982. The show mimics the way we actually process our own histories. It’s not a straight line; it’s a web.
The Kate and Tully Dynamic: It’s Not Just "BFFs"
We need to get real about the power dynamic here. Tully Hart is a force of nature. Katherine Heigl plays her with this desperate, vibrating need to be loved that’s masked by extreme confidence. She’s the one who gets the guys, the fame, and the money. But she’s also the one who has nobody to go home to.

Kate is the anchor. Sarah Chalke does some of her best work here, playing the "stuttering" middle-aged woman who feels like she’s lost herself in motherhood and marriage.
- Tully needs Kate to feel grounded.
- Kate needs Tully to feel alive.
It’s codependent. It’s arguably toxic at times. But it’s also the most honest portrayal of a long-term friendship I’ve seen on TV in a long time. They fight. They say things that are meant to draw blood. Then they show up at each other's door with a bottle of wine because who else is going to understand?
The show draws heavily from Kristin Hannah’s novel, but it takes liberties. Big ones. The book is more of a slow burn, whereas the show leans into the melodrama. If you’re a fan of the book, the changes to Tully’s career trajectory and her relationship with Max (Jon-Michael Ecker) probably felt like a lot. But for TV, those stakes had to be higher.
That Ending: What Happened Between Tully and Kate?
Okay, we have to address the elephant in the room. The funeral.
The season starts with a funeral tease. Most viewers—myself included—spent the whole season terrified that Tully or Kate was in that casket. When we finally get to the church in the finale, we realize it’s not one of them. It’s Kate’s father, Bud.
But the real shocker isn't the death. It’s the standoff outside the church.
Tully pulls up, looking for her best friend, and Kate looks at her with a coldness that feels like ice water. She tells Tully she never wants to see her again. She says what Tully did was "unforgivable."
What did Tully do?

In Firefly Lane season 1, we don't get the answer. The show creators left us hanging. It was a brilliant, frustrating move. In the book, the fallout is caused by a segment on Tully’s talk show that makes Kate look like a bad mother. On screen, the tension had been building for years, fueled by jealousy, secrets, and the way Tully often bulldozes Kate’s life.
The Supporting Cast and Subplots
While the girls are the heart, the men in their lives add the necessary friction. Johnny Ryan is the standout. He’s the war correspondent who loves Kate but is seemingly enchanted by Tully’s energy. The 80s scenes where he and Kate are falling in love while trying to keep it professional are genuinely sweet.
Then there’s Max. Tully’s romance with the younger EMT felt like a genuine turning point for her. For a moment, it looked like she might actually choose a "normal" life. The miscarriage subplot was handled with a surprising amount of nuance, showing how Tully’s trauma from her own childhood makes her petrified of being a mother herself.
And let’s not forget Cloud. Beau Garrett plays Tully's mom across forty years, and she’s heartbreaking. She represents the "what if" in Tully’s life—the constant fear that she’s destined to be as broken and unreliable as her mother.
Addressing the "Fluff" Criticism
Is the show "soap opera-y"? Yes. Absolutely. It’s got the lighting of a Hallmark movie at times and some of the wigs in the 70s sequences are... a choice.
But calling it fluff misses the point. The show deals with heavy themes:
- Generational Trauma: How Tully’s relationship with Cloud dictates her inability to trust.
- The Erasure of Women in the Workplace: Seeing Kate and Tully navigate the 80s newsroom is a sharp reminder of the casual sexism of the era.
- The Identity Crisis of Motherhood: Kate’s struggle to find a "self" outside of being Marah’s mom or Johnny’s wife.
These aren't light topics. They’re the backbone of the female experience for a huge demographic.
How to Get the Most Out of Your Rewatch
If you’re heading back into Firefly Lane season 1 before diving into the later episodes, keep your eyes on the background. The show uses color palettes to help you keep track of where you are in time.

- The 70s: Everything is warm, sepia-toned, and soft. It’s the "golden hour" of their friendship.
- The 80s: High contrast, bright colors, and sharp edges. It’s the peak of their ambition.
- The 2000s: Cool blues and greys. It’s the "winter" of their lives, filled with more regret and realism.
Watch the way Tully looks at Kate’s family. In the 70s, she’s an outsider looking in. In the 80s, she’s trying to build her own world. By 2003, she’s basically a member of the family, yet she’s never felt more alone. It’s a tragic arc that the show handles with a lot of grace.
Actionable Insights for Fans
If you finished season 1 and are feeling that "post-show blues," here is how to actually process it and move forward.
Read the Book, But Don't Expect a Twin
Kristin Hannah’s Firefly Lane is a masterpiece of commercial fiction. However, the show changes significant plot points. If you want the "real" ending as the author intended, read the book. Just be prepared to cry more than you did during the show.
Watch for the Musical Cues
The soundtrack isn't just background noise; it’s a narrative tool. Songs like "Goodbye Yellow Brick Road" or "She’s Got a Way" are placed specifically to mirror the emotional state of the characters in that specific year. Pay attention to the lyrics during the big transitions.
Check the "Fly Away" Sequel
Many people don't realize there is a second book called Fly Away. It focuses heavily on the aftermath of the main story and gives a lot more backstory on Cloud. If you found yourself fascinated by Tully’s messed-up family tree, that’s your next stop.
Evaluate the "Tully" in Your Life
The show is a great mirror. Are you the Kate or the Tully? Most of us are a bit of both. Use the show as a prompt to reach out to that one friend you haven't spoken to in six months. Life is short, and as the 2003 timeline shows, you never know when a "forever" friendship might hit a wall.
The brilliance of this first season lies in its refusal to give easy answers. It challenges the idea that "BFFs" means everything is always perfect. Sometimes, the person who knows you best is the person who can hurt you the most. That’s the core of the Firefly Lane experience. It’s messy, it’s loud, and it’s deeply human.
