WARNING: The following article contains spoilers for "What You Take With You," Season 6, Episode 9 of The 100.
A major character ever since The 100's first season in 2014, Henry Ian Cusick's Kane, has officially met his untimely end in the latest episode of the popular CW series.
Horrified that he had his consciousness transferred into a new host body from his ailing original one, Kane decided to eject himself and other Nightblood into space to prevent them from being used by the Primes to prolong their lives. Cusick and longtime showrunner Jason Rothenberg both confirmed Kane's departure from the series.
Kane had been introduced in the post-apocalyptic series' pilot episode as an antagonistic councilman who sent the titular 100 teenagers and young adults to a devastated Earth in an effort to rebuild human civilization. Over the course of the series, he had become a more sympathetic figure, even forming a romance with longtime character Abby Griffin.
With Kane's heroic sacrifice, the Primes' scheme to use new Nightblood from Earth has effectively been dashed, setting them on the stage for a final confrontation against the crew of the Eligius IV and the Children of Gabriel for their own mortality.
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.
