Since his return to County, Luka has become obsessed with treating and streeting patients as quickly as possible. He argues with Pratt over the treatment of a pregnant woman who doesn't want her premature baby to receive life-saving treatment, as well as with Romano, who wants more tests ordered on patients so that the hospital can make some money. Abby is still on her surgical rotation and Romano is still riding her hard. Coop flirts with Chen. Susan has been reading to Ben Hollander in her spare time and he seems to have developed a crush on her. Luka meets Sam's son Alex in the new JumboMart (which has replaced the fire-damaged Doc Magoo's).
