“You’re Tully fuckin’ Hart,” Kate reminds her best friend in the trailer for Firefly Lane Season 2. The supportive moment is one of many we’ll see in the upcoming second season of the series, which follows the ultra-tight friendship of Tully (Katherine Heigl) and Kate (Sarah Chalke) over the years. Played in their teenage years by Ali Skovbye and Roan Curtis and as adults by Heigl and Chalke, respectively, Tully and Kate’s friendship spans three decades from their childhoods on Firefly Lane to their adult lives in 2004.

Tully and Kate’s 30-year-strong bond has always felt unbreakable, but at the end of the first season, we learned that something had, in fact, come between the besties. In Season 2, we’ll find out exactly what could potentially end that decades-long friendship. And thanks to the new trailer, we know we’ll also see Tully taking her voice back after quitting her eponymous talk show, Kate and her ex-husband Johnny (Ben Lawson) weathering his accident in Iraq, and Tully starting her career over from scratch with a quest to find out more about the father she never met. 

In the flashback storylines, we’ll see Kate and Johnny fall in love, Tully having a fling with a promising sportscaster in the newsroom and teenage Tully and Kate weathering their first long-term separation when Tully’s mom, Cloud (Beau Garrett), is arrested for dealing drugs.

But there’s one thing you can always count on in Firefly Lane: All roads will ultimately lead Tully and Kate back to each other.

In addition to the trailer, you can check out some new photos — featuring new hairstyles, new characters and lots of warm embraces — above. The first part of Firefly Lane Season 2 premieres Dec. 2.
