Later on, Steve allowed the other interns to practise on epidural anaesthesia on him, and introduce a catheter onto his male organs; because of this he couldn't move for a while and thus was not present at Sadie's operation. Dr. Yang found him immobilised and thus found out about the operation. Steve was put on probation along with the other interns.

It's revealed in the sixth season that Steve and Megan got married, and concluding that he was the father.

The patient, however, succumbs to complications due to the inherent nature of the IL-2. This has shown to affect Swender's otherwise authoritarian and impartial persona, and casts doubt on this treatment-protocol.
Dr. Margaret Campbell Faye Dunaway 5
A general surgery attending and Seattle Grace's first female surgeon. With forty-years of surgical experience, she is considered a pioneer and one of the hospital's most respected surgeons; it is implied that, in that time, Richard Webber was taught by her as she recalls an incident involving a clamp dropped into an open body cavity, and has worked with Ellis Grey.

Derek and Rose shared a kiss and were dating, much to Meredith's distress as she tried to get over him. Despite their seemingly happy relationship, Rose was soon bothered by comments made by hospital personnel about Meredith and Derek's break-up only being temporary which ended up being true when Derek and Meredith get back together for good. For example, Addison Montgomery sarcastically called Rose the "McRebound," unaware that Rose was in the room. Her prediction proved correct when in the season finale, "Freedom," Derek and Meredith make up and share a kiss. Derek abruptly leaves this kiss to break up with Rose, signalling the end of their relationship. Afterward, Rose was hostile towards Derek whenever she saw him but when she accidentally cut his hand during a surgery, she apologised and transferred to peds.
Dr. Finn Dandridge Chris O'Donnell 2, 3
The former veterinarian of Meredith and Derek's dog, Doc. He was also the newest love interest for Meredith for some time before she broke up with him because she was still in love with Derek.

He dated Meredith throughout the end of the second season, and the beginning of the third season. He competed with Derek Shepherd for Meredith's heart and ultimately lost to Derek because Meredith was still in love with him. Meredith realised that he may be the "best guy," but he wasn't "her guy." After she told him this, he replied by saying, "He'll break your heart again Meredith, and when he does, I won't be here" and walked out for the last time.
Dr. Benjamin "Ben" Warren Jason George 6, 7, 8
Anaesthesiologist from Mercy West Hospital and boyfriend of Miranda Bailey until she broke up with him after the shooting, finding herself unstable to be in a relationship after such a traumatic experience. Ben tries to stay away from Miranda after that, but they eventually start working together again. He's then asking Miranda about her new relationship with nurse Eli. Bailey wants him to stay out of her life. However she eventually ends things with Eli and reunites with Ben. As he wants Bailey to move in with him, she tells him to take it slow. He proposes to Miranda during the show's eighth season, which she accepts.

An incompetent paediatric surgery attending brought on as the interim Chief of Paediatric Surgery when Arizona Robbins gave her notice to oversee a paediatric surgery program in Malawi, Africa. Under contract for a year, Stark continues to serve as the department chief when Robbins returns. Described as a lazy doctor and a complacent and self-satisfied attending, Stark represents the antithesis of attending surgeons commonly employed at Seattle Grace/Mercy West Hospital.

Self-proclaimed as being "damn good at her job," Fields attended Harvard Medical School and completed her OB/GYN residency at Duke University Medical Center. Fields is also Callie Torres's obstetrician and shows that she is equal parts tough, ironic and empathetic, especially when dealing with Torres and her support team; Mark Sloan and Arizona Robbins. It also seems that she has a slight crush on Alex Karev, and in episode 18 they start to form a relationship. Also, Dr. Addison Montgomery comes back and is told that she is not able to deal with traumatic pregnancy cases. (Callie being pregnant in a car accident). Alex Karev breaks off the relationship he had with her in the season seven finale.

Other Minor CharactersEdit

  • Joe the Bartender (Steven W. Bailey): The owner of the Emerald City Bar, located across from the hospital, where the doctors often go for a drink. Joe collapsed due to an aneurysm in "Raindrops Keep Falling on my Head", and Derek and Burke performed a stand-still surgery to repair it. Joe and his boyfriend Walter attended the Thanksgiving Izzie hosted at Meredith's house, and they went on a camping trip with Dr. Shepherd, Burke, Webber, Karev and O'Malley. During this trip, Joe revealed during a discussion with the Chief that although he and Walter had been "on-and-off" for about ten years, they were now committed and considering the possibility of children. They are one of two couples being considered as adoptive parents for a young mother's twins.
  • Walter (Brian Reid/Jack Yang): Joe's boyfriend. Walter has been played by Jack Yang in all of his appearances except in the episode "Let It Be", where he is played by Brian Reid.
  • Bonnie Crasnoff (Monica Keena): A patient admitted to Seattle Grace Hospital after being in a train crash. She and another passenger, Tom, were connected by a large metal pole passing through their bodies. Since moving the pole would kill them, the doctors decided to move one of the patients off the pole, then operate around the pole to repair the damage in the other patient. Since her injuries were more severe, they decided to move her, and she died almost immediately. Bonnie reappeared in season three as part of Meredith's dream after drowning.
  • Dennison "Denny" Duquette, Jr. (Jeffrey Dean Morgan): A patient waiting for a heart transplant. He developed a close relationship with Izzie Stevens, and eventually proposed to her. Izzie risked her career to save him by cutting his LVAD wire, insuring that he would become so ill that he would get a new heart. He died shortly after the transplant from a blood clot. He reappeared in season three, as part of Meredith's dream after drowning, and again in season five. Izzie began to see Denny everywhere, which was eventually revealed to be a symptom of her brain tumour. He first appeared in the season two episode, "Begin the Begin", and made his last appearance in the season five episode "Here's to Future Days".
  • Dylan Young (Kyle Chandler): The commanding officer of the Seattle PD bomb squad that responded to the bomb scare. He helped to keep Meredith calm as she held the bomb located inside a patient's body. She removed the bomb safely from the patient, but it exploded while Dylan carried it out of the OR. He reappeared in season three as part of Meredith's dream after drowning.
  • Amanda (Shannon Lucio): A young woman saved from being hit by a bus by George, who was subsequently dragged several yards by the bus. Amanda was extremely concerned about him, and she stayed with him in the ICU and referred to him as "her prince." She attended George's funeral and cried harder than his own mother. Amanda kept a daily vigil outside the hospital until Izzie confronted her, pointing out that she was still alive thanks to George, and that she should honour him by living her life.
  • Rebecca Pope or Ava (Elizabeth Reaser): A patient suffering from amnesia after being badly injured in the ferry crash. She was discovered by Dr. Alex Karev, and they developed a very close relationship. While at Seattle Grace, she delivered a baby girl and underwent facial reconstruction surgery, performed by Dr. Mark Sloan. She eventually regained her memory and went home with her husband, Jeff, although before leaving she pleaded with Alex to "give her a reason to stay." She returned six weeks later claiming to be pregnant with his child. Although initially upset, Alex eventually became excited about having a baby with her; however, it was revealed that she was suffering from a hysterical pregnancy. When she attempted suicide, Izzie intervened and had her admitted to the psychiatric ward.
