As Grey's Anatomy prepares to return to ABC on October 15, the network is slowly revealing the names of guest actors who will appear at Grey Sloan Memorial Hospital. Recently, Deadline reported that James Wolk, known for his role in the acclaimed series Mad Men, will join the medical drama to play Seth Norton, a surgeon who will work with the hospital to open a new VIP area. This is just one of several new faces that viewers will encounter in season 23 of Grey's Anatomy. In addition to Wolk, Deadline has confirmed that three new guest stars will join the series: Sarah Levy, Martin Martinez, and Trevor Tordjman. Sarah Levy, who played Twyla Sands in the popular sitcom Schitt's Creek, will portray Corrie, a young woman who is pregnant and described as "spiritual and a bit eccentric." She is anxious about giving birth due to a traumatic experience during the birth of her first child. Martin Martinez, who appeared in Magnum, will play Charlie, a character who "had a difficult childhood and, due to the traumas he experienced, has a hard time trusting others." Trevor Tordjman, known for his role in the Disney movie franchise Zombies, will play Thomas, a "charming and lively boy who doesn't realize how attractive he is." Thomas visits the hospital to check on his brother's girlfriend. These characters will add new storylines and dynamics to the already complex world of Grey's Anatomy. However, French audiences will have to wait until next spring to see these new characters on screen, as the series will not air on TF1 until then. This delay means that while the rest of the world can enjoy the new season on ABC, French viewers will have to wait a bit longer for the same content.
