The problem they face: if they go into the splinter facility, the causality could screw up everything they've worked for. Undo it all. But Cassie is dead-set on finding Olivia. And there was an arrest in 1971 that Cassie wants to follow up on.

The team decide to sneak into the facility and try to use the machine "one time before the first time." If they can kill Olivia, none of this will have happened, The Witness will not ever have lived. As Cole watches the preparation for his first jump, the gang come up with a plan.
