Contracts renewed for four 'Grey's Anatomy' newcomers HOLLYWOOD, June 15 (UPI) -- The actors who play four interns on ABC's "Grey's Anatomy" had their contracts renewed for the 10th season of the medical drama, The Hollywood Reporter said. Camilla Luddington, who plays Jo, Alex's (Justin Chambers) love interest; Gaius Charles, who plays Shane, who wants to be a brain surgeon; Jerrika Hinton, who plays Stephanie, Jackson's (Jesse Williams) love interest; and Tessa Ferrer, who plays Leah, who nearly lost her job in Season 9, will all return next season. The fifth new intern from Season 9, Tina Majorino -- who played Heather, a goofy, promising brain surgeon favorited by Patrick Dempsey's character, Dr. Dereck Shepherd -- was not renewed, The Hollywood Reporter said Friday. Majorino is a series regular on TNT's "Legends" and is reprising her role as Mac in the upcoming "Veronica Mars" movie. It's unclear if fellow "Grey's Anatomy" newcomer Hilarie Burton, who plays Lauren, will return to continue a potential romantic plot with Jessica Capshaw's Arizona.
