The final installment of Firefly Lane drops on Netflix *so* soon. Naturally, it's time to catch up on everything Kate Mularkey and Tully Hart. In case you're unfamiliar (or if it's been a while), Firefly Lane is the story of lifelong besties Tully Hart (played by Katherine Heigl) and Kate Mularkey (played by Sarah Chalke), and the show takes viewers on a journey watching the women grow from gangly teens with big dreams into strong women in their forties.

The first part of season 2, which dropped in December 2022, provided a few answers to big, lingering questions people had like, ya know, why Kate and Tully are no longer friends after decades of friendship. However, if you feel a little antsy waiting for part 2 to find out whether Tully and Kate ever make amends or if Kate is going to be okay after that cliffhanger from part 1, you're not alone.

Luckily, the show is based off of Kristin Hannah's popular novels Firefly Lane and Fly Away, so there are some insights into what’s in store. Here’s what the Firefly Lane book ending reveals, and what might be in store in the final episodes, releasing on Netflix on April 27:

Wait, why are Tully and Kate not speaking to each other?

For those behind on their Netflix watch list, allow me to catch you up to speed. Later in life, Kate and Tully find themselves locked in a love triangle. Here's the gist: Kate was married to Johnny. They got divorced, but then started seeing each other again. However, Kate struggles with the fact that Johnny was once in love with Tully and that the two even slept together in the past.

While Kate was the one who ended up marrying Johnny (and having kids with him), Kate can't seem to shake the fear that Johnny might still be in love with Tully.

Tensions between the besties really came to a head, though, when Tully invites Kate and her daughter, Marah, to appear on her show, The Girlfriend Hour, where Johnny works as a producer, per PEOPLE. While the segment is initially supposed to help this mother and daughter duo work out their issues (they can't stop fighting), it turns out that Kate is actually on the segment to represent "overbearing moms," the outlet says.

Kate is (obviously) less than pleased about this, and ends up storming off the show. So, that's basically why Kate and Tully stopped speaking.

Do Tully and Kate become friends again?

Yes, these two BFFs do make amends, but it’s still not under the best circumstances. They start talking again after Kate gets diagnosed with terminal breast cancer. Based on the trailer for the upcoming episodes, Kate's therapist recommends she reaches back out to Tully.

In the book, Kate reaches out to Tully, while she's on assignment in Antarctica, but can't reach her. (Because, Antarctica.) Kate then reaches out again during her treatments and finally gets ahold of her old friend. Tully flies back home immediately to be with her.

In the season 2 part 2 preview, it seems the Antartica plot line makes the show, considering a clip of Tully seeing 18 missed calls from Kate on her Blackberry (don't you miss those?) It also looks like Kate and Tully end up reuniting at some point during the end of season 2.

Kate dies of breast cancer.

In what is a total heart-crusher, Kate doesn't make it. But before she dies, Kate writes a letter to Tully, asking her to help raise her kids with Johnny, even suggesting she’s okay with the idea of Tully and Johnny getting together. (For the record, Johnny says that he only ever loved Kate.)

"I know you'll be thinking that I left you, but it's not true. All you have to do is remember Firefly Lane, and you'll find me. There will always be a TullyandKate," Kate writes, per Oprah Daily.

It's unclear what exactly will happen in the Firefly Lane TV series, but FWIW, Kate looks like she gets pretty sick in the trailer.

In the next book, Tully tries to deal with the aftermath.

In Fly Away, the Firefly Lane sequel, Tully helps Johnny raise Kate’s children. Things aren’t seamless, though, and Tully deals with alcohol abuse and prescription drug issues. She also gets into a serious car accident and is "reunited" with Kate while she's in a medically-induced coma, Marie Claire says.

Heads up: Season 2 is the last of the Firefly Lane series on Netflix, and it doesn't seem like there will be much shown of Tully's life after Kate dies, according to the trailer. The show could also have an alternative resolution, which has been done before to change sad endings (à la My Sister's Keeper).

The final installment of Firefly Lane drops on April 27. You can watch the first half of season 2, streaming now on Netflix. But as far as all this stuff goes in the book's ending, well, you'll have to wait and see if the TV show follows suit!
