Second Thoughts - S0.E3

Liber8's internal power struggle takes a mega-violent turn as Sonya and Travis recruit gangs as their weapons. Kiera investigates a new (to 2013) street drug that she recognizes from the future. The drug, called "flash" in 2013, is administered by eye drops and allows the user to remember vividly events from the past. Alec is part of a group in a car in which the driver had taken the drug. It crashes and Alec ends up with an arm in a sling. He was also given a plastic ampule of the drug but had not taken it. Kiera learns that Sonya is paying the gang she had recruited to kill Travis with flash. Kiera and Carlos track one of the gang members to the lab where it is being produced and a gunfight ensues in which many of the gang members present are killed. Sonya is there and targets Keira, but neither is successful in their attempts to kill the other. Travis calls members of various gangs together for a meeting and presents them with the heads of their former leaders.
