An incident occurs that bears remarkable similarities to an early case in the original time-line, though there are some notable differences. Olivia's memories of the new time-line continue to fade, and Broyles places her on temporary leave, but her memories of original case assist Peter and Lincoln. Lincoln gets infected with a virus and Walter must figure out a cure.
