Complete story — includes the ending
In 2044, Cassie's hallucinations worsen. The time machine suddenly malfunctions, transporting people from random points in the timeline into the temporal facility, including soldiers from 1959 and horribly mutated former test subjects for Project Splinter, with whom the team members are confronted. Eckland sacrifices himself to prevent the time machine from destroying the facility. When Cole and Ramse try to power down the machine, Cassie takes Sam hostage and holds him at gunpoint to stop them. Cole and Ramse realize she is under the influence of the Witness, who used her to sabotage the machine. To snap her out of her trance, Cole has Ramse shoot him, knowing she will not let him die. Ramse shuts down the power, but Sam is struck by a backlash of temporal energy and splinters. Jones administers Cassie a drug to prevent the Witness from possessing her again, and a grieving Ramse leaves the temporal facility. Sam is met in an unspecified time period by an unseen figure.
