According to Yang, Steve stinks and has memory problems which won't let him become a doctor, but he will dig ditches by the side of the road instead. In the episode "In The Midnight Hour", Steve allowed the other interns to practice an epidural anesthesia 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 immobilized and found out about the operation. Steve was put on probation along with the other interns. Later on the season, Steve slept with fellow intern Pierce's girlfriend Megan after they broke up, and she got pregnant without knowing who is her baby's father. It's revealed in the 6th season that Steve and Megan are married, and have concluded that he's the father. Later during the merger, Megan is fired, but Steve keeps his job, although she's later hired back by Derek Shepherd.

Intern Pierce	Joseph Williamson	4, 5, 6	23
A surgical intern of Dr. Alex Karev, who considered to give him to George O'Malley just because he hates how his name sounds.

Dr. Swender	Kimberly Elise	5	3
A surgical oncology attending assigned to oversee Izzie Stevens' cancer treatment. She is said to be the best surgical oncologist in the state of Washington. Swender is a proponent for IL-2-use as treatment for cancer; she reasons its success when a patient, initially given only three months to live, uses the therapy and survives an additional two years. 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	1
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.

A nurse at the hospital. She works often with Dr. Derek Shepherd. She has been the attending nurse on over 30 of Dr. Derek Shepherd's surgeries, as Rose stated in "Forever Young" (Episode 8, Season 4). 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 breakup only being temporary. 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, signaling 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 apologized and transferred to a different department.

Family members

Meredith and Lexie's family

• Thatcher Grey (Jeff Perry): Thatcher is Meredith and Lexie Grey's father and the ex-husband of Ellis Grey. They were married for about seven years before his wife began having an affair with Richard Webber. Eventually, Ellis's affair and time away from home put too much strain on their marriage, and Thatcher left. Meredith was a small child at the time of the divorce, and roughly twenty years would pass before they saw each other again. Thatcher blames Ellis somewhat for his estrangement from Meredith, saying Ellis was "cold" and wouldn't let him get to know his daughter. After the disintegration of his first family, Thatcher married his second wife, Susan, and had two more daughters, Lexie and Molly. Susan constantly encouraged him to renew his relationship with Meredith. However, Susan died very suddenly at Seattle Grace Hospital, following a rare complication from a routine procedure to treat her hiccups and acid reflux problems. Meredith had been the intern on Susan's case, so Thatcher lashed out at Meredith and blamed her for Susan's death, slapping her in the face at one point. He later forbade Meredith to come to Susan's funeral service. In the episode "Physical Attraction, Chemical Reaction," Lexie and Alex find Thatcher extremely drunk. Alex humiliates Thatcher by offering to buy a drink for him. Lexie tells Alex to keep this a secret from Meredith. Thatcher later comes in the ER looking for Meredith, and she actually enjoys his company as a drunk more than his sober state. Later, as Lexie and Meredith talk, Meredith suggests Lexie watch him more, prompting Lexie to lash out at her. She tells Meredith that Thatcher is always drunk and swings from being proud of Lexie to berating her. At first Meredith doesn't believe it until Lexie relates how Thatcher uses the same "lifetime of proud" line with Lexie as he had with Meredith. This pushes Meredith to let her father go at last from her life. Thatcher returns in the fifth season, having gone through rehab and apologizing to both daughters, Meredith is cool to Thatcher, but Lexie is willing to forgive him.
• Molly Grey-Thompson (Mandy Siegfried): Molly is 22 years old and is Lexie's younger sister, and Meredith's other half-sister. She is also Thatcher Grey’s daughter by his second wife, Susan.

Originally a patient at Mercy West, Molly transferred to Seattle Grace at 32 weeks pregnant, and Addison operated to repair a congenital diaphragmatic hernia on Molly’s baby. She later gave birth to a baby girl, whom she named Laura. Her mother, Susan, died after rare complications after a simple surgery. Molly can be seen with her father at the hospital, before attending her mother's funeral.

Dr. Webber's family

• Adele Webber (Loretta Devine): The outspoken wife of Dr. Webber, Adele has been shown to perceive much more than her husband might expect — whether it is about the past of her own marriage, or the current state of the Shepherds'. She endured her marriage silently and without complaints, but she finally had enough when Richard put his other hospital patients above her dying niece. When Richard failed to return home on the night of the prom, she made an appointment to see him at the office, but was blown off because of another hospital emergency. It proved one too many, however, and she gave him an ultimatum: her or the hospital. Richard tried to avoid making the choice, but Adele was tired of his indecision, and left him. When Dr. Richard Webber quits his job as the Head Of Surgery, he returns to Adele to find out that she has moved on and appears to be involved with another man. She is in the process of divorcing Richard when she was involved in a small car accident, and was hospitalized. She revealed to Addison that she is pregnant. After being released, she fainted in a bathroom and was found by Richard. It is discovered that she is having complications with the pregnancy and will have to undergo surgery. Despite the fact that he believes that he is not the baby's father, Dr. Webber stays at his wife's side even when she tells him to leave her be. This support eventually brings them back together. After the surgery, Adele lost the baby and tells Richard that the baby was indeed his and that there was never any other man in her life.

She is also a devout Catholic as evident by her disapproval of George and Callie getting a divorce and in tears asks George to go to church and pray for forgivness.

When she arrives in the hospital, Bonnie is cracking jokes, and seems to be in no pain. We later learn that her body is supplying itself with adrenaline, which is keeping her from feeling the full extent of her pain. As time progresses, the doctors at Seattle Grace decide they must come to a decision quickly about how to proceed with Bonnie and Tom. They quickly realize one of them must be pulled off the pole which speared them together. Whichever patient is removed from the pole has a very slight chance of surviving the trauma. After deliberation, the doctors decide Bonnie must be pulled off the pole, because she has a very little chance of surviving either way. When Bonnie is told about this, she is strong, and even though Tom insists they remove him, Bonnie tells them she is ready. She is put to sleep, and slowly removed form the pole. Directly after being removed, the doctors begin to operate, in an attempt to save her life. Too much damage has been done, and she soon dies. Monica Keena reprises her role as Bonnie in Season 3, on Episode 17: Some Kind of Miracle. This time, Bonnie is in a kind of semi-afterlife, seemingly "stuck" in the hospital, unable to accept the circumstances of her death, which the main character, Dr. Meredith Grey, finds herself in after drowning. Bonnie does not seem as sweet this time around, as she insists that they should have tried harder to save her. She tells them she should not have been allowed to make that life or death decision while drugged on painkillers. Another change in Bonnie is that she is visibly healthy. The audience is led to believe the damage of the pole is gone. However, at times, Bonnie begins to bleed where the pole was, and goes through the pain over and over.

• Susan Grey (Mare Winningham): Susan was the second wife of Thatcher Grey, and had two children with him, Lexie and Molly. She was Meredith Grey's stepmother. Meredith often referred to her as her "surrogate mother". Susan was always aware of Thatcher's first wife and daughter, and had reached out to Meredith, offering to include her in their family and encouraging her to develop a relationship with Thatcher. At first, Meredith was resistant to Susan's desire to mother her, but she later became accepting of it and the two became friendly. She died suddenly, following a rare complication from a routine procedure to treat her hiccups and acid reflux problems, leaving Thatcher devastated and turning to alcohol in his grief.

• Harold O'Malley (George Dzundza): The father of George O'Malley and two other sons, Jerry and Ronnie, the O'Malley patriarch was a truck driver with a passion for vintage cars. He was married for 40 years to his wife, Louise, and took great pride in all his sons. In addition to taking his sons turkey hunting every Thanksgiving, Harold also took the boys on frequent camping trips during their childhood. His diagnosis with esophageal cancer which had spread to his stomach, in addition to a leaking aortic valve, was a huge blow to the O'Malley clan. Harold underwent surgery to replace his aortic valve, and later underwent a second surgery to determine the extent of the cancer. Prior to the second surgery, he had asked Dr. Webber and Dr. Bailey to remove the tumor regardless of the risk in order to give him a chance to fight the cancer. The surgery proved too much for his body, and after several days, he went into multi-system organ failure, which prompted the family to take him off life support.
• Dr. Charles Percy (Robert Baker): Mercy West resident working at Seattle Grace after the merger. Percy was shot by the husband of one of Dr. Shepherd's former patients. He died in Miranda Bailey's arms. His last words were of his love for Reed and that Dr. Bailey was his favorite surgeon.
• Dr. Reed Adamson (Nora Zehetner): First victim of the massive shooting at Seattle Grace Mercy West Hospital. She worked for Mercy West before the merger and was shot in the center of her forehead without ever knowing what happened. Dr. Alex Karev then came to see what the explosive noise was before he himself was shot.

• Gary Clark (Michael O'Neill): His wife was admitted as a patient to Seattle Grace under Dr. Webber and Lexie Grey. She ultimately went into a coma, and had signed a DNR, prompting Derek to tell them to take her off life support, a decision that Clark felt was not his place to make. Clark later files a lawsuit against Derek for wrongful death, but loses. In the season 6 finale, he returns to the hospital looking for Derek, and he asks Dr. Reed Adamson where to find him, and she sneers him off, so he shoots her in the head, then shoots Alex Karev in the side when he comes to see what happened. Clark has a vendetta for Derek, and also Richard, and Lexie, since all three were involved in his wife's case. He wounds and kills many other people in the hospital, and finally finds Derek, and after some debate, shoots him in the chest. He ultimately comes to a choice whether to shoot Dr. Webber, or shoot himself, when he only has one bullet left. Dr. Webber tells him that he's not afraid to die, but asks Clark if he is. Clark finally decides to end his own life right before the S.W.A.T. team arrives.
