Isobel Katherine "Izzie" Stevens, M.D. is a fictional character from the medical drama television series ''Grey's Anatomy'', which airs on the American Broadcasting Company (ABC) in the United States. The character was created by series producer Shonda Rhimes, and was portrayed by actress Katherine Heigl from 2005 to 2010. Introduced as a surgical intern at the fictional Seattle Grace Hospital, Izzie worked her way up to resident level, while her relationships with her colleagues Meredith Grey (Ellen Pompeo), Cristina Yang (Sandra Oh), George O'Malley (T.R. Knight) and Alex Karev (Justin Chambers) formed a focal point of the series. Heigl was critical of the character's development during the show's fourth season, particularly her romance with George. She declined to put herself forward for the 2008 Emmy Awards, citing insufficient material in the role. After speculation that Izzie would be killed off in the fifth season, the character was diagnosed with Stage IV metastatic melanoma. She married Alex in the series' one-hundredth episode, and afterwards, her tumor was successfully removed. Izzie made her final appearance in the sixth season, leaving Seattle after Alex ended their relationship. Heigl requested to be released from her contract 18 months early, in order to spend more time with her family. In January 2012, Heigl reported that she would like to return to ''Grey's Anatomy'' to give closure to her character. ==Storylines== Izzie appears in the first episode of ''Grey's Anatomy'', meeting fellow interns Meredith Grey, Cristina Yang, George O'Malley and Alex Karev. She and George move in with Meredith and become best friends. Izzie's boyfriend, hockey player Hank (Jonathan Scarfe), struggles to accept her new role as a surgeon, and the two break up. Izzie is hurt when Alex exposes her past as a lingerie model. However, the two later go on to begin a friendship and then a romance. Alex experiences sexual dysfunction with Izzie and cheats on her with nurse Olivia Harper (Sarah Utterback). When Izzie finds out, she breaks up with him, though they briefly reunite following a bomb incident at the hospital. Izzie reveals that she had a daughter at the age of 16 and that she was sent to adoption while treating a pregnant teenager. Izzie falls in love with cardiothoracic patient Denny Duquette (Jeffrey Dean Morgan), and the two become engaged. When Denny's condition deteriorates, Izzie deliberately worsens his health further by cutting his LVAD wire to move him up the donor register. Although Denny receives a new heart, he has a stroke hours later and dies. Izzie is the sole beneficiary of Denny's will, inheriting $8.7 million. She uses the money to open a free clinic at the hospital: the Denny Duquette Memorial Clinic. Izzie disapproves of George's relationship and marriage to orthopedic resident Callie Torres (Sara Ramirez). She and George sleep together, and attempt to keep their liaison a secret. George and resident Miranda Bailey (Chandra Wilson) are the only people aware that Izzie gave birth to a daughter at the age of sixteen; ultimately the child was given up for adoption. He supports Izzie when her daughter Hannah (Liv Hutchings), diagnosed with leukemia, arrives at Seattle Grace Hospital in need of a bone marrow transplant from Izzie. Izzie's feelings for George grow, and she reveals that she has fallen in love with him. When Callie discovers George has been unfaithful, the two separate, and George and Izzie embark on a short-lived relationship, only to discover there is no real chemistry between them. Izzie supports Alex when he discovers his new girlfriend has psychiatric problems, and convinces him to have her committed. She is also handed primary responsibility for the clinic, as Bailey cuts back on her responsibilities. Izzie and Alex go on to rekindle their relationship, though Izzie is concerned when she begins hallucinating Denny. She discovers she has metastatic melanoma (Stage IV) which has spread to her liver, skin, and brain, causing the hallucinations. Her survival chances are estimated at only 5%. She is admitted to Seattle Grace as a patient, and Derek Shepherd (Patrick Dempsey) successfully removes a tumor from her brain. Izzie spends her time in the hospital planning Meredith and Derek's wedding, but when her condition worsens and Derek discovers a second brain tumor, they give the ceremony to Izzie and Alex, who marry in front of all their friends. The procedure to remove the second tumor from Izzie's brain causes her to lose her short-term memory, and although she soon regains it, she flatlines moments later. The fifth season ends with her friends ignoring her DNR order and attempting to resuscitate her, transposed with images of Izzie in an elevator encountering George, who has been in an accident and is also currently flatlining. Though George dies, Izzie is resuscitated and recovers enough to return to work. Izzie makes a treatment error that endangers the life of a patient, and is fired from the hospital's surgical program. Believing Alex is partially to blame, she writes him a Dear John letter and leaves. Izzie later learns that Alex was not responsible for her lost job, and returns to make amends with him, but Meredith informs her that Alex is moving on. Izzie informs Alex that she no longer has cancer. Although he is pleased, Alex officially breaks up with Izzie, telling her that he loves her but deserves better. She leaves Seattle to start fresh. Several episodes later, Alex informs Meredith that Izzie sent divorce papers, which he signs in the episode "How Insensitive". In the sixth season finale, Alex is shot and asks for Izzie. Imagining that Meredith's half-sister Lexie (Chyler Leigh) is Izzie, he apologizes and asks her never to leave him again. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Izzie Stevens」の詳細全文を読む スポンサード リンク
