Suits' Sarah Rafferty has joined Grey's Anatomy as a recurring character.

The actress will be part of a medical mystery which is set to play out over a number of episodes, according to TV Line.  She will make her debut in the episode which is due to air on January 30 in North America. Rafferty will play Suzanne, a patient who comes to Grey Sloan Memorial for a seemingly routine procedure. However, she soon develops "puzzling compilations" which are set to leave the doctors stumped. Grey's Anatomy will be returning from its midseason break on January 23 in North America. And fans are no doubt going to be hoping for resolutions to some of the bigger cliffhangers, including what happened at Joe's; the fact that there are sparks flying between Dr. Cormac Hayes (aka: 'McWidow') and Meredith; and that Amelia twist. Showrunner Krista Vernoff recently revealed that the show is going to be "sexier" when it returns in 2020. Grey's Anatomy will be returning to its original timeslot of 9pm, where it aired for eight seasons until it moved to 8pm in 2014. “There are different rules for a 9 PM show than there are for an 8 PM show, and we hope to take advantage of those rules,” Vernoff told Deadline about the change. “Grey’s was definitely allowed to be a sexier show when it was on at 9 o’clock. So we are excited by the change back to our original (Thursday) time slot.”
