( April 2020 ) ( Learn how and when to remove this message ) In the woods, Diyoza is approached by Jade, a Sanctum guard who offers to let Diyoza's child be raised in Sanctum if she saves Rose from the Children of Gabriel. The Children of Gabriel are torturing Octavia for information about any hosts (Nightbloods) they have from Earth. Tosh suggests killing Octavia and Rose but Xavier wants to take them to their "Old Man." While the CoG are arguing, Octavia escapes with Rose. The CoG run after them but Diyoza arrives just in time to kill a few and rescue them. However, Tosh ultimately kills Rose. Octavia and Diyoza team up to hunt the remaining Children of Gabriel and their leader, the Old Man. In Sanctum, it's Delilah's Naming Day and part of the ceremony involves making amends. Clarke embraces it but Raven refuses to accept her apology. After the ritual, Delilah comes back as Priya VII and doesn't recognize Jordan. Cillian turns out to be a spy for the Children of Gabriel. He paralyzes Clarke before getting caught in the act and deciding to slit his own throat rather than surrendering to interrogation. Since Clarke is a Nightblood, Russell and Simone take advantage of her paralyzed state to use her as a host for their daughter, Josephine, rather than have to wait a further 56 years for another host to mature at the cost of wiping Clarke's own mind, apparently killing her. After Clarke is mind-wiped, the Lightbournes insert Josephine's mind drive into her head, resurrecting Josephine in Clarke's body.
