The 100: Revolution Comes to Sanctum

WARNING: The following article contains spoilers for The 100 Season 6, Episode 10,"Matryoshka," which premiered last week on The CW.

After arriving on Sanctum in the Season 6 premiere of The 100, the last survivors from Earth discovered the majority of the planet's population is ruled by the Primes, who are revered as gods. It was eventually revealed the Primes' secret of immortality involved transferring their consciousnesses into new host bodies, allowing them to live on for centuries. After learning the crew of the Eligius IV possessed individuals compatible with the mind-transfer process, the Primes welcomed them into their community, before their secret was exposed. In the latest episode, tensions between the Primes and Eligius IV crew finally come to a head, with bloody consequences.

The Prime Ryker had quietly begun to question the morality of possessing host bodies, inspired by the Eligius IV mechanic and pilot Raven Reyes. Ryker finally chooses to side with the Eligius IV crew, and reluctantly joins with Echo and Gaia to sow dissent against the Primes among the populace of Sanctum. Ryker tells a man named Ty, who sacrificed much for the Primes, that his long-held beliefs are actually an elaborate lie. That culminates into a full-on rebellion against the Primes, with Ty assassinating Simone, who had just returned from the Eligius IV after the passengers thwarted the Primes' plot to create new Nightblood, the blackened, radioactive resistant blood that made the mind transfer process possible.

Simone's death marks only the latest Prime killed since the Eligius IV arrived on Sanctum, which doesn't go unnoticed by the Prime leader Russell, Simone's husband. Russell originally planned to send the last survivors from Earth on their way, uncomfortable with bringing outsiders into his carefully managed community. However, with Nightblood inhabitants beginning to dwindle among the local populace, desperation led Russell to change his mind after learning that Clarke Griffin possessed the blood necessary for the mind transfer.

That decision led to the deaths of several Primes throughout Season 6, including one at the hands of the young Nightblood, and Clarke's adoptive daughter, Madi. Falling further under the influence of a mental projection known as the Dark Commander, Madi began a killing spree in retaliation for Clarke's possession by the Prime Josephine, before being stopped. In the wake of the recent losses and the bloody civil unrest, Russell orders the capture of the latest arrivals from Earth, and plans to burn them at the stake.

Ultimately, Russell relents yet again, this time convinced by Clarke's mother Abby, the Eligius IV's physician, that new Nightblood can be created by harvesting bone marrow. Having previously vowed to resurrect Simone through a new host body, Russell agrees, but only if Abby performs the procedure on Madi first due to her murderous actions. As Abby and the others are released, Russell has Ty executed for killing Simone and to instill a sense of order and justice back into the community.

Russell's desperation to find more compatible host bodies has already cost the Primes a number of their own, as the crew of the Eligius IV upset the society the Primes reigned over for 200 years. And with Clarke now free of Josephine and teamed with the Primes' greatest enemy, Gabriel, and his rival faction, their fragile control of Sanctum may be quickly coming to an end.

The 100 airs on The CW Tuesdays at 9 p.m. ET/PT. The series stars Eliza Taylor, Paige Turco, Marie Avgeropoulos, Bob Morley, Henry Ian Cusick, Lindsey Morgan, Richard Harmon and Tasya Teles.'
