Season 4 episode 8 of the TV series "The 100" will see Clarke (Eliza Taylor) and Abby (Paige Turco) wrestle on the consequences of human experimentation. Will they experiment on one person to save the rest of humanity?

A synopsis for this episode reveals that after a disappointing discovery, Clark and Abby question how far they are willing to go. Meanwhile, Jaha (Isaiah Washington) finds a lead to the mysterious "Second Dawn."

The official trailer for this new episode shows a battle of morality. Abby is hesitant to use a human being for the experiment that could probably save people's lives.

However, there is a scene showing that the radiation level is being turned up. This could mean that she finally decides to proceed with the experiment.

It can be recalled that, in the previous episode, Emori (Luisa D'Oliveira) was afraid that she would be chosen as the subject of such experiment, so she set up an "assault" by a "Grounder." 

The trailer, however, shows the experiment failing. It is interesting to know, if that really happens, whether Abby would have to refine the Night Blood and choose another test subject.

The trailer also briefly shows someone hitting Kane (Henry Ian Cusick). A screen capture would show that this is Indra (Adina Porter). Indra was last seen before the "black rain" came. A lot of people died when the "black rain" first hit Arkadia. Indra's daughter, Gaia (Tati Gabrielle), is also returning this week.

On the other hand, Jaha can be seen going out on a new expedition. This is something that fans have been watching out for, apparently, because the last expedition turned out badly for everyone.

Jasper is also seen in the trailer. Despite having suicidal tendencies, he survived the "black rain".

"The 100" season 4 episode 8 titled "God Complex" will air on Wednesday, March 29, at 9 EDT on The CW. Omar Madha directed this episode which was written by Lauren Muir.
