The second and final season of Firefly Lane dropped on Netflix this month, so naturally, everyone has been busy catching up on all things Kate Mularkey and Tully Hart. In case you're unfamiliar (or if it's been a while), season 1 told 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 Dec. 2, provides a few answers to big, lingering questions people have like, ya know, why Kate and Tully are no longer friends after decades of friendship. But since part 2 doesn't drop until 2023, there are still a lot of unknowns. The show, of course, is based off of Kristin Hannah's popular novels Firefly Lane and Fly Away, so it only makes sense to that the novel's ending might provide some insights into what’s in store. Here’s what the Firefly Lane book ending reveals:

Why are Tully and Kate not speaking to each other?

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.

Things 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 less than pleased about this and ends up storming off the show. So, that's 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, per Marie Claire.

Kate reaches out to Tully, who is on assignment in Antarctica, to tell her about her diagnosis, 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.

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.

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 split into two parts, with the first part out on Dec. 2 and the next in June of 2023, according to Katherine Heigl.
