As Skaikru continues to search Becca’s Island for ways to avert the coming nuclear apocalypse on THE 100, their troubles are just beginning back at home with the Grounders. King Roan (Zach McGowan), who believes he’s been betrayed, is marching an army toward Arkadia, intent on taking their ship to save his own people. Clarke (Eliza Taylor) is now fighting a war for survival on two fronts, and she’s going to need all the help she can get if they want to stay alive.
In this week’s new episode, titled “The Tinder Box,” an almost dead Octavia (Marie Avgeropoulos) manages to warn her people about Azgeda, just in time for Clarke to race against the clock and come up with a plan to stop Roan’s soldiers. Clarke will make a desperate plea to a former allied force with Bellamy (Bob Morley) and Kane’s (Henry Ian Cusack) lives hanging in the balance.
Elsewhere, Abby (Paige Turco) and Eric (Sachin Sahel) aren’t making much progress in figuring out how to use Nightblood to protect everyone from radiation. They’ll have much bigger problems to worry about though when Raven (Lindsey Morgan) starts having a bad reaction to her new abilities brought on by A.L.I.E.’s chip.
Check out some sneak peeks from the new episode below. THE 100 airs tonight (March 1) at 9:00 p.m. ET/PT on The CW.
