"She'll be the guest director of our musical," Sachs said — which several of the cast members seemed to think was a joke at first. ("I have questions!" exclaimed AnnaLynne McCord, who plays bad girl Naomi.) But it's totally true. As Judah said after the session, the producers met with Doherty and pitched her several ideas, one of which was the drama teacher story. She'll be helping the cast put on Spring Awakening, though Judah wouldn't go so far as to say Doherty will be signing or dancing.
A CW press release filled in Brenda's backstory a bit more: after the original 90210 wrapped up, Brenda headed to London to study acting, became a successful actress in London and New York, and then moved into directing. West Beverly High managed to petition her to return as a guest director. The deal makes Doherty the fourth original cast member to make the transition to the new show: Jennie Garth, Tori Spelling, and Peach Pit proprietor Joe E. Tata will also be back.
