Katherine Heigl returning to Grey’s Anatomy

Katherine Heigl has annocunced that she will be back for Grey’s Anatomy. Unfortunately it doesn’t look like T.R. Knight will be returning to the medical drama. In the season finale everything was left up in the air with Heigl’s character having brain surgery and Knight’s getting hit by a bus. Brain surgery is definitely the way to go. He looked unrecognizable after the accident.
