She is able to detect which symbols are the correct ones to press by listening to the sounds. When the door to the Cadogans' quarters is opened, Becca hears ultrasonic frequencies coming from the stone. She says she is "here to help" and is invited inside the bunker once they see her breathing the irradiated Earth's air. Tristan is exposed to radiation and Becca secretly gives him Nightblood serum, known only to Callie. He has supposedly tried over a million combinations but has failed to get the seven correct symbols.Ģ years later, Callie and Reese are scavenging on the ground with radiation suits when they spot Becca Franco's escape pod from her spaceship, Polaris. In the Cadogans' quarters, Bill reveals the Anomaly Stone, which he stole from Machu Picchu and believes will allow him to save the human race. She and another boy, August, attempt to open up the bunker to let more people in, but are stopped by Reese, Callie's brother, and Tristan, a loyal cultist. Once arriving in the bunker, Callie learns that there is room for more people.
Callie and her mother, Grace, head off to the Second Dawn bunker, leaving behind Callie's friend Lucy because she is not a level 12 in the Second Dawn. Bill Cadogan's daughter, Callie, is on a video call with Cadogan when it is revealed that the bombs are in the air with the codeword 'Anaconda', hence the episode name. Most of the episode is a flashback to the early days in the Second Dawn Bunker. This is interesting because Gabriel knows that the Flame is no longer in Clarke's head, suggesting that the people on Bardo are not aware of its whereabouts. Gabriel explains to Clarke that "the key" is the the AI in her head. He understands Trigedasleng because it was created by his daughter Calliope. She recognizes him from Jaha's tablet shown to her in " The Four Horsemen". On Bardo, Clarke meets the Shepherd, who is indeed Bill Cadogan of the Second Dawn.
