Synopsis for "Ring of Truth, Part IV"
Allison Mann has discovered why Ampersand and Yorick Brown are the only two males to have survived a global gendercide: material from the monkey's feces uniquely synthesized with Yorick's biology.[1] As she explains the details, Agent 355 returns from her confrontation with the Setauket Ring with an injured Hero Brown in tow. Before Hero can explain herself, Yorick assaults her for killing Sonia.[2] Yorick storms out as Toyota observes them, waiting for an opportunity to abduct Ampersand.
On the roof of Allison's laboratory, Agent 355 gives some photographs to Yorick: his sister has been following their every step across America, taking notes on how all of his friends and loved ones are doing. Agent 355 is convinced that she is recovering from the brainwashing done by the Daughters of the Amazon and she also helped her recover the engagement ring that Yorick plans to give Beth Deville. Hero still struggles with hallucinations of Victoria, whom she stabs to death in a vision while she's sedated.
Tokyo takes her chance to finally abscond away with Ampersand.
