5. Bodies of Water

Complete story — includes the ending

In 2044, Jennifer sends Cassie to 2016 to get the Primaries' identities from her younger self. Desperate to get rid of Deacon, Cole and Ramse betray him to one of his enemies, the Foreman. Deacon kills the Foreman, and instead of retaliating, congratulates the duo on becoming as ruthless as he. In 2016, the Witness gives Olivia a new mission: find and prepare Cassie. Cassie and Jennifer return to the latter's old home, which triggers childhood memories of Jennifer's mother trying to drown her. Cassie comforts Jennifer, who is then able to tell Cassie another Primary's name: Kyle Slade. The Pallid Man captures them, and Olivia gives Cassie a hallucinogen. In a vision, Cassie sees Aaron's face behind the Witness's mask. Jennifer breaks loose and sees a manuscript, "the Word of the Witness," containing her death date: September 23, 2044. She rescues Cassie and stabs Olivia. The Witness puts the Pallid Man in charge of the Army's mission, replacing Olivia. Cassie tells Cole about Slade and decides to stay in 2016 to look after Jennifer. In 1975, Slade senses that Cole is coming for him.
