KELLY HU GUEST STARS AS DC COMICS VILLAIN CHINA WHITE — Oliver heads to the courthouse to get his death certificate repealed and is pleasantly surprised to run into Laurel, who is there prosecuting Martin Somers (guest star Ty Olsson), a criminal with ties to the Chinese Triad. Oliver recognizes Martin's name from his father's book and sets his sights on taking him down. Martin orders the Triad to "take care of" Laurel so they send their top mercenary – China White (Hu) – after her, an act that culminates in a battle between Arrow and China White. Meanwhile, Moira and Walter (guest star Colin Salmon) ask Oliver to take over the company. Colin Donnell, Willa Holland, David Ramsey and Paul Blackthorne also star. David Barrett directed the episode with story by Greg Berlanti & Marc Guggenheim and written by Andrew Kreisberg & Marc Guggenheim.
