A.L.I.E. and the Mount Weather folks may have been defeated on THE 100, but an even bigger problem is going to emerge in season 4 of the show: the threat of nuclear meltdown. A.L.I.E. warned Clarke that the planet’s nuclear reactors were essentially self-destructing, which means that everyone would die from the excess radiation poisoning. But Clarke chose to end the false promise of the City of Light and killed A.L.I.E. regardless, which means she now has to figure out how to save the world from this new problem.
When the show returns, it’s all about surviving. People start dying from radiation poisoning and it’s a race to save the world. Will the other clans turn on Skikru because of Clarke’s choice? Meanwhile, Octavia is more fully embracing her new Grounder behavior.
Season 4 of THE 100 premieres on Wednesday, February 1 at 9:00 p.m. ET/PT on The CW.
