Multiple traumas come to the ER after a truck crashes into a coffee bar, narrowly missing a very pregnant Carol. Rumors fly around the ER about Anspaugh retiring as chief of staff and Romano taking his place; the rumors are later found true. Mark speaks out against Romano in a staff meeting. Weaver double-crosses him to move ahead with her career and is later named permanent chief of the ER. Carter meets his cousin's ex-wife, whom he is attracted to. Reggie proposes to Jeanie, and she decides to adopt an HIV-positive baby. Benton and Carla meet with a mediator. Lucy asks Weaver to mentor her; Weaver turns her down because she is the new chief and it would be inappropriate. Two new doctors are introduced: Dr. Luka Kovac, a Croatian doctor moonlighting in the ER, and Dr. Cleo Finch, a pediatric resident in the ER.
