Plot summary
Sarah runs to a nearby diner, where she is quickly confronted by two armed men, one of whom is Mark Rollins, who attempt to bring her in. They kill the diner's owner (who shoots one of the men in the process), but Sarah manages to escape. She finds Felix and gets Alison to give them access to an unregistered gun so she can get Rachel to bring her to Kira and Mrs. S, as she believes Dyad has kidnapped them. Sarah impersonates Cosima at Dyad to steal Leekie's passkey and confronts Rachel, who reveals she does not have Kira.
Alison, who tries to kick her addiction to pills, is chosen as the lead in the community musical, replacing the now-dead Aynsley. Leekie wants Cosima to start working for Dyad. With nowhere else to go for help, Sarah goes to Art's home with the intention of telling him the whole story. Art, who is investigating the diner shooting, identifies the perpetrators as Proletheans; they are likely the ones who have Kira. Meanwhile, a wounded Helena stumbles into a hospital.
