For the first time since Patrick Dempsey’s surprise exit from Grey’s Anatomy last week, his onscreen wife, Ellen Pompeo (Meredith), is speaking out. In a Twitter post titled “Happy Monday,” she says she is “excited to tell the story of how Meredith goes on in the face of what feels like the impossible.”

Apparently the veteran ABC show’s fans aren’t nearly as excited. They’ve launched a petition to bring Dr. Derek Shepherd back. It’s already collected more than 29,000 signatures.
