Orion in the Sky (S08E18)

While Greene tries to distract himself from his worsening brain tumor by working hard, he reluctantly recognizes that his debilitating illness is hampering his ability to perform the job. Watching other terminally ill patients struggle with their treatments also has a sobering effect on him. Greene has a poignant reunion with his ex-wife, Jenn (recurring guest star Christine Harnos), and mediates between the staff and a stubborn but deluded homeless man, Al Ervin (Paul Benjamin). Confident, young first-year intern Gregory Pratt (recurring guest star Mekhi Phifer), who has transferred from another hospital, hopes to become a resident at County General soon--but first he must heed advice from Greene about his bedside manner as they treat a family man, Stan Seidel (Ken Lerner), who receives the terrible news that he has advanced prostate cancer. Meanwhile, Abby moves out of Kovac's apartment when her abusive neighbor leaves her building. An Egyptologist, Willa Goldman (Blaire Baron), is hospitalized for a rare disease. And confusion over an elderly woman's wishes results in heroic measures to resuscitate her. (Warner Bros. UK)
