Alycia Debnam-Carey and Rhiannon Fish on The 100

There was a lot happening in Thursday’s (Feb. 11) episode of “The 100.” Between Clarke’s (Eliza Taylor) failed attempt on Naya’s (Brenda Strong) life, Lexa’s (Alycia Debnam-Carey) successful attempt on Naya’s life, the epic fight between Lexa and Roan (Zach McGowan) and Pike (Michael Beach) being elected chancellor back at Arcadia, viewers may have missed a little something that’s going to prove very important to the show.

At Polis, Lexa is training a group of youngsters as to who should be next in command should anything happen to her. What they all have in common is their “night’s blood,” or black blood. Not only is the night’s blood an indicator of who can be in command of the Grounders, but Naya’s right-hand woman Ontari (Rhiannon Fish) also has night’s blood.

Executive producer Jason Rothenberg isn’t saying much about what exactly night’s blood means, but he does reveal to Zap2it that the night’s blood is important.

“The night’s blood is important, yes. It’s important. I don’t think we’d come up with something that’s so weird just to be weird,” says Rothenberg. “It’s cool, though. That is something that is in the show for a reason.”

To find out just what that reason is, keep tuning in Thursdays at 9 p.m. ET/PT on The CW.
