Octavia confronts Bellamy over his relationship with Echo and reiterates the latter's banishment. Diyoza's ship arrives, delivering apples and offering free passage to any Wonkru defectors. Octavia offers Echo a deal; spy on her people and report anyone that plans to defect in exchange for her banishment to be lifted. Monty eventually deduces that he will need to access the firewall from the inside; Echo, who has decided against Octavia's plan, offers to instead go undercover as a defector so that she can breach Diyoza's camp. Octavia agrees, but has Cooper to shoot fleeing defectors, ostensibly for appearances. Murphy and Emori work to remove his shock collar and decide to use his collar to set up an explosive trap. During which time they discuss and rekindle their relationship. The two find McCreary survived the explosion and take him hostage. Clarke believing that Octavia will figure out and kill Madi for her natural Nightblood status, plans to leave with the defectors. Madi objects, fearing for Clarke's safety, and reveals her status to Octavia. Octavia tells Clarke that nothing bad will happen to Madi and that Madi will train as a Wonkru warrior. Echo successfully infiltrates Diyoza's camp.
