On the Grey’s Anatomy episode “Something Against You,” there’s a lot of personal business being hashed out. Penny (Samantha Sloyan) finally stands up for herself against Meredith (Ellen Pompeo) -- and Bailey (Chandra Wilson) urges Ben (Jason George) to kick out roommate Jackson (Jesse Williams). But the highest point of personal tension arises when a "Doctor Nathan" shows up at the hospital and dives right in to treat a patient. Maggie (Kelly McCreary) calls him out and wants to know what his credentials are. When Owen (Kevin McKidd) discovers Nathan in scrubs, he goes ballistic. The mysterious Dr. Nathan is someone from Owen’s past who will, according to McKidd, turn Owen’s life "upside down.”
Dr. Nathan is portrayed by Martin Henderson. The Australian-born actor is best known for his roles on the popular Australian TV series Home and Away (Geoff Thomoas), Sweat (Tom Nash), Big Sky (Scotty Gibbs), Off the Map (Dr. Ben Keeton), Secrets & Lies (Ben Gundelach), and currently, The Red Road (Harold Jensen). Americans will recognize Henderson from the 2015 film Everest as Andy “Harold” Harris. Grey’s Anatomy airs Thursdays at 8pm on ABC.
