In this gripping chapter of The Witnesses, Fidel and Vera continue their journey through the scriptures, stepping beyond Eden into a world now shadowed by jealousy and betrayal. They meet Cain and Abel — two brothers whose paths could not be more different.

As Cain wrestles with rejection and the weight of his pride, he is lured into a secret covenant with Lucifer himself. Fidel and Vera watch helplessly as the first murder unfolds, changing the course of history. Cain is marked and cast out, but the darkness doesn’t end with him. A rebellion rises. A generation is deceived. And as Fidel begins to drift into that same darkness, Vera is left with one burning question: Can love bring someone back from the edge?

A story of loss, temptation, and the power of sibling love, this episode explores the cost of choosing darkness—and the courage it takes to shine in its midst.
