Varrick's assistant who later marries him is Zhu Li.
Zhu Li begins as Varrick's exceptionally capable personal assistant, often carrying out his eccentric instructions with the brisk command, “Do the thing!” Although she initially appears mainly as comic relief, the series gradually reveals how much of Varrick's business and survival depends on her intelligence, loyalty, and practical judgment.
In Book Four, Zhu Li challenges Varrick after years of being treated as subordinate rather than as an equal. She appears to cooperate with Kuvira, but this is part of a plan to sabotage Kuvira's spirit-energy weapon. After Kuvira's defeat, Varrick proposes to Zhu Li, and they marry during “The Last Stand,” the series finale.
Viewers sometimes confuse Zhu Li with Ginger, the actress Varrick employs in his movers, or with Opal and Eska, who have separate storylines. Zhu Li is also later elected president of the United Republic of Nations, succeeding Raiko.
