Sarah is finally convinced by seeing CCTV security footage from the initial transformation. Richard comes up with a formula that would effectively destroy the female part of himself, but he must consume it as Helen within a certain time frame. To avoid letting her escape, Richard handcuffs his hands and straps his feet to a bed. After he transforms, Sarah attempts to inject Helen with the formula but fails—injecting only about 20% of it, causing random body parts to spontaneously transform between male and female. A fire breaks out in the apartment and Helen manages to escape.
