Which two "ER" characters got married in the episode "I Don't"?

In ER, Abby Lockhart and Luka Kovač got married in the episode “I Don’t.” Their surprise wedding took place during the show’s 13th season, after Luka arranged a ceremony that reflected Abby’s discomfort with a large, traditional wedding.

Abby and Luka’s relationship had developed gradually through years of working together at County General Hospital. Luka, a Croatian physician, had experienced profound personal loss during the Balkan Wars, while Abby struggled with alcoholism, family instability, and the demands of medical training. Their contrasting histories made their relationship one of the show’s more complicated romances.

The wedding was deliberately unconventional: Luka planned it quickly, and Abby initially resisted the idea of being pushed into a ceremony. The episode’s title, “I Don’t,” plays on the expected phrase “I do” and signals Abby’s uncertainty about marriage. Viewers sometimes confuse this wedding with other ER ceremonies, including Neela Rasgotra and Michael Gallant’s later wedding.
