ABC just announced that Neve Campbell is joining the cast of the long-running emo doctor drama!…….

We’re told the Party of Five vet and new mommy is set to “appear in multiple episodes” as Patrick Dempsey‘s…(wait for it)… sibling!

Grey’s lovers know McDreamy has four sisters, two of which have already appeared on the show. So, Mz. Campbell will be playing either Kathleen the psychiatrist or his mysterious fourth sis.
