Complete story — includes the ending
A massive battle breaks out between Jones's group and the Army of the 12 Monkeys, with the Daughters and the West VII soon joining in. Cassie confronts Olivia and, after a fight, shoves her into a temporal energy beam, splintering the upper half of her body into the distant past, where it becomes the corpse from which the virus originated. Cassie nearly lets time collapse so she can be with Cole forever, but Cole talks her out of it, and she stops the countdown before the Red Forest paradox initiates. Ramse, Jennifer, and Cassie are sent back to their own times while Cole and Jones share a last conversation before Jones dies. Cole loads the Primaries' program into the time machine and activates it, erasing himself from time. A new timeline is created in which time travel is never invented. James Cole, the virus, and the Army of the 12 Monkeys never come to exist, and everybody else lives a different life. Cassie, however, remembers what happened. Cole finds himself on a beach, where Jennifer tells him that Jones modified the program to reinsert him into the new timeline. Cole and Cassie each find their way to the farm house where they once lived together, and the two begin their hard-earned happy ending.
