The CW has released an official description with spoilers for the December 2 episode of Crazy Ex-Girlfriend.
The title of the episode is “Who Needs Josh When You Have A Girl Group?” and the notion of “drama between Rebecca and Paula” doesn’t sound too pleasant. Here’s the write-up:
REBECCA AND PAULA DRIFT FARTHER APART — When Rebecca (Rachel Bloom) tries to host a girls’ night with Paula (Donna Lynne Champlin) Heather (Vella Lovell), and Valencia (Gabrielle Ruiz), things don’t go as planned. Meanwhile, Darryl (Pete Gardner) bonds with co-worker Maya (guest star Esther Povitsky) and discovers they have more in common than he realized. Vincent Rodriguez III and Santino Fontana also star. Jack Dolgen wrote the episode, directed by Stuart McDonald (#206). Original airdate 12/2/16.
