And by "might," I mean she definitely will, because the only contingencies are reportedly storyline and cash, two things the show's producers would be out of their minds not to give her. Brenda Walsh returning to 90210 would be ratings gold, and I have to admit, I am dying to see her square off with Kelly Taylor again (she's got it coming!), as well as with the new characters played by Lori Loughlin and Jessica Walter (a Brenda vs. Gangy fight would make Dynasty's epic Alexis and Krystle battles look like Wall-E holding a basket of kittens!). That is, at least for the four of five episodes Doherty will last before she starts fighting with the other cast members and has to be written off the show a la the original 90210 series and Charmed. Sigh.
