"The death wave will be here in 10 days. This really is our only hope."

So says Clarke in the trailer for the latest installment The 100 Season 4 Episode 8, but it's unclear who she's really trying to convince – everyone else or herself.

On The 100 Season 4 Episode 7, the group at Becca's lab made the decision to use a scavenger they caught for human experimentation, in the hope of creating a nightblood solution allowing everyone to have the radiation resistance that Luna has.

Clearly, no one is particularly comfortable with the plan – but as Clarke says, it's their only chance of survival. But will it fail and be a moot point anyway in the end?

Check out these images from The 100 Season 4 Episode 8 below for a hint of what's to come, and tune in to watch "God Complex" on Wednesday, March 29 at 9/8c on The CW.
