Y: The Last Man #5

Agent 355 leads Yorick Brown and Ampersand to meet Allison Mann. Meanwhile, the Daughters of the Amazon are trailing to intercept him and find a woman who has a motorcycle that the group used to own and Hero Brown proves her loyalty by killing her.

In Mann's laboratory, she reveals that she has previously cloned her own nephew and brought the child to term in her uterus. At the moment he was born, the gendercide occurred that killed all organisms with a Y-chromosome and even all stored sperm; she believes she is personally responsible somehow. When she sees Ampersand and Yorick, she becomes convinced that he may be the cause of the gendercide and attempts to draw blood from the two, causing the monkey to jump out the window.

A few hours later, Alter Tse'Elon arrives, on the hunt for Yorick, but they depart to try to find him and set the laboratory on fire before they go. When Mann and her companions return, they find Mann's work destroyed and debate if they should return to the White House to get new instructions, head to California for a back-up laboratory site, or head out to Australia to find Beth Deville, Yorick's fiancee.
