Tzi Ma
Clark Gregg reprises his role as Coulson from the film series, starring alongside Ming-Na Wen, Brett Dalton, Chloe Bennet, Iain De Caestecker, and Elizabeth Henstridge. Louis Ozawa Changchien portrays the super-powered man Chan Ho Yin, while Ruth Negga is introduced as Raina—the titular "girl in the flower dress". In addition, to support the episode's Hong Kong setting, actor Tzi Ma appears in a guest role as a Hong Kong agent of S.H.I.E.L.D., and Jeremy Zuckerman contributed performances on Chinese instruments for the musical score. The episode brings back elements from the series' pilot, and features ties to the MCU films.
