The night Kate dies, Jack loses consciousness and wakes up at the exact moment they first met, with all his memories intact.

By the final loop Jack combines every lesson he has learned — about honesty, love, and letting go of control — and Kate survives.

In the second timeline, Jack theorizes his mission, recognizes the damage his obsession causes his friends, and confronts the weight of good intentions going wrong. The third timeline forces Jack to witness Franny's pain up close and earn his trust, only to lose it again through secrecy. In the fourth timeline, avoiding Kate entirely destroys the friendship between Franny and Jillian, and Franny pays the ultimate price when a stranger shoots him. Each revelation strips away another illusion of control, until Jack finally accepts he cannot fix everyone — and that honesty, not strategy, is what love requires.
