See You Yesterday

In the final moments of “See You Yesterday,” CJ takes a last, daring trip back in time, using her scientific invention to alter the past once more. Her goal is to save her brother Calvin, who was murdered, and in doing so, she hopes to change everything. The science behind their time travel involves manipulating protons within a wormhole, with the constraints that they can only go one day into the past and have just ten minutes to make a difference before the wormhole collapses. Despite her efforts, CJ’s previous attempts to alter history do not go as planned; her friend Sebastian dies during a previous time jump, and Calvin himself doesn’t survive the original attempt. However, something extraordinary happens when Sebastian’s death is overwritten by CJ’s new trip — Calvin is resurrected. This moment signifies that by changing Sebastian’s fate, CJ inadvertently brings her brother back to life, effectively rewriting the history she knew.

Calvin, although never fully aware of the scientific complexity behind CJ’s actions, recognizes her in a heartfelt moment before he sacrifices himself for the greater good — to prevent a future tragedy. His last words, “See you yesterday,” are a poignant nod to their bond and the science fiction journey they shared. CJ’s last trip emphasizes her willingness to sacrifice her comfort to ensure her brother’s survival, even if it means risking the fabric of reality. The movie concludes with CJ wearing her brother’s dog tags, a symbolic reminder of her connection to Calvin and the sacrifices made. In the end, the film leaves viewers with a sense of hope and the enduring power of love and family, showing that sometimes, to truly save someone, you must be willing to face the unknown — and run toward it, into the past, with faith that life can be altered through science and sacrifice.
