What is Luke's surname in the TV series?

Luke’s surname in *The Handmaid’s Tale* television series is Bankole.

His full name is Lucas “Luke” Bankole, played by O-T Fagbenle. Luke is June Osborne’s husband before the rise of Gilead, and the couple attempts to flee with their daughter, Hannah, after the new regime begins stripping women and dissidents of their rights.

Luke’s previous divorce creates a legal problem under Gilead’s theocratic system. Because his earlier marriage was not recognized as properly dissolved, Gilead declares his relationship with June invalid, labels June an adulteress, and treats their daughter as illegitimate.

Viewers sometimes confuse Bankole with names belonging to other major characters. Waterford is Fred’s surname, Blaine is Nick’s, and Putnam belongs to Commander Warren. Luke initially appears to have been killed during the escape attempt, but the series later reveals that he survived and reached Canada, where he works to reunite with June and Hannah.
