When Crazy Ex-Girlfriend returns for its third season on The CW, it鈥檒l bring everything from the sexiest song the show has ever done to a soaring, Disney-style, huge-ensemble musical number, plus a new credits sequence.

The new credits were directed by a pro.

Crazy Ex-Girlfriend is known for its credits sequences, which feature some of the show鈥檚 most complicated songs. 鈥淚t鈥檚 the most arduous, the most talked-about songwriting process,鈥 says star Rachel Bloom of writing the opening credits every season. But for season three, they鈥檝e enlisted a music video pro to help out 鈥 Joseph Kahn (鈥淟ove the Way You Lie,鈥 鈥淏ad Blood鈥) is directing the credits, and also episode four, which Bloom says is 鈥渁 very important episode鈥 to the show.

Season three is chapter three.

The new season is the third chapter in this four-part book, though co-creator Aline Brosh McKenna says that four chapters don鈥檛 necessarily equal four seasons. But it definitely makes planning easier.

鈥淥ne of the things everyone on the show likes is that we do know where the story鈥檚 going. 鈥 We do have four distinct chapters worked out,鈥 says McKenna.

Chapter three is 鈥渞evenge.鈥

鈥淚f you thought this show was going to be 鈥榝unny Fatal Attraction,鈥 that鈥檚 what we鈥檙e going into this season as. Rebecca thinks that she is a woman scorned,鈥 Bloom reveals. 鈥淚 am a sexy, strong woman scorned.鈥

She adds that since Rebecca equates sex with power, she鈥檚 going to be putting her sexuality out there in order to try to regain her power, which means there鈥檚 a super-sexy musical number coming.

鈥淚 actually have a fairly big bruise on my arm from a very acrobatic, probably the sexiest musical number we have ever done on the show, in which I actually have my boobs out. First time in 35 episodes,鈥 says Bloom, to which McKenna cracks, 鈥淭he writers room was like, it only took 35 episodes for us to get Rachel to fling her boobs around. But we got there!鈥

Revenge isn鈥檛 the only theme, though.

Star Vincent Rodriguez III reveals that while Rebecca is definitely out for revenge against Josh after getting burned in season two, this chapter is also about Josh reexamining his own life.

鈥淚t鈥檚 also that Josh is gonna hit a crossroads, because how long does he really stick with anything?鈥 says Rodriguez III. 鈥淲here does Josh see himself in the future? That鈥檚 a struggle 鈥 That鈥檚 something he鈥檚 going to have to face head-on, and Rebecca鈥檚 going to actually help facilitate that, given her revenge-seeking bullet for me.鈥

Rebecca and Paula also have some growing to do.

鈥淲ith any good relationship and with any sort of excellent writing, that relationship is organic and it is realistic in that it is constantly moving and reshaping and figuring out what it is,鈥 says Donna Lynne Champlin. 鈥淭his season is a continuation of, how do Paula and Rebecca support each other in a healthy way and an unhealthy way? 鈥 Our relationship is constantly evolving, depending on what is happening in both of our lives.鈥

She also reveals that the show is going to follow Paula home to Buffalo to see her parents. 鈥淵ou get more information about who Paula is and who Rebecca is, which fills in the colors more about why we do what we do,鈥 says Champlin.

Crazy Ex-Girlfriend returns Friday, October 13, at 8pm ET/PT on The CW.
