While Kathleen and Juliette plot how to steal the vaccine from the Scarlets for Roma, another worker rebellion begins in Chenghuangmiao. Nearby, a group of White Flowers kills anti-gang protesters. Juliette comments that she used to think Shanghai was becoming hateful, but now believes it has always been so. Marshall spies on Benedikt, pays off many messengers, and returns to the safe house, worried that a Nationalist soldier has recognized him.

Juliette returns to Chenghuangmiao, where the riot is already quelled, to help Roma break into the Scarlet vaccine lab. She shows Roma a pile of the vaccine, which has been made in solid form. It is easily dissolved in water but flammable when solid. The Scarlets intend to put it in the water supply in their territories, mass vaccinating only their people—Tyler’s plan. Kathleen arrives with Rosalind tagging along. Rosalind is surprised to see Roma and resents that Juliette can decide when the blood feud does and does not matter. She leaves for her shift at the club. Juliette goes to distract Tyler, and Kathleen leads Roma into the lab. Unlike Roma, Kathleen clearly sees that Juliette doesn’t wish to harm him. Roma hurriedly grabs papers, and he and Juliette leave while Kathleen takes her turn to distract Tyler.
