Demetri and Agent Banks attempt to track down a killer as questions arise about the universe course-correcting itself, when people who thought they'd escaped their fates are found dead; Mark reluctantly agrees to help Simon find his sister, Annabelle, but discovers he's withholding the truth about her true circumstances; the FBI discovers the identity of Suspect Zero; and Nicole learns the whereabouts of Keiko - the woman in Bryce's flashforward - but struggles with whether to share this information, due to her growing feelings for him.

A character mentions the van was tracked to an 8 block area. Another character says there are 100 ways out of the area so they could not be covered. This is incorrect, since if every one of the 8 blocks went outside the area (no dead end roads or T intersections), the maximum number of ways out would be 32: 8 blocks x 4 sides. See more
