In 2016, Cole persuades Jennifer not to release the plague. He and Cassie destroy Jennifer's supply of virus, altering history, although they, Ramse, and Jones still remember the previous timeline thanks to the time-travel drug. After Cole stops Cassie from killing Ramse, she splinters to 2044 with the latter, abandoning Cole in 2016. Jennifer takes Cole to the Emerson Hotel, where the manager gives Cole the key to room 607, which Cole purchased in 1944. Inside, Cole finds a photo of him and Cassie from 1944. Jennifer, feeling purposeless after deciding not to start the plague, attacks and seduces Cole, then cuts herself. Cole calms her and tells her to find a new purpose, and she leaves. In 2044, history has changed: the plague began a few years later, and Jones has a lover, Dr. Eckland, of whom she has no memory. Deacon and Cassie unsuccessfully interrogate Ramse about the Messengers. The older Jennifer has the Daughters force Jones to retrieve Cole from 2016, repaying him for helping her younger self. Cole talks with Cassie about how his actions have affected her and how saving, not killing, people is the only thing he has done that changed history. He leaves Cassie to contemplate the 1944 photo.
