Who ultimately helps Vincent with his identity swap in GATTACA?

In "GATTACA," Vincent's identity swap is primarily facilitated by Jerome, who is a genetically superior individual and provides his identity to Vincent, allowing him to navigate a society that heavily discriminates based on genetics. Jerome's generosity and willingness to help Vincent stems from their shared experiences and the bond that forms between them as they each strive to overcome the limitations imposed by a society obsessed with genetic perfection.

Jerome's contributions go beyond simply providing a new identity; he also assists Vincent in carefully crafting his persona, ensuring that all aspects of Vincent's life align with the identity he is assuming. This partnership is crucial to Vincent’s ability to pursue his dreams of space travel under the guise of an individual who was genetically engineered for success. The trust and reliance on each other signify deeper themes of friendship and sacrifice central to the narrative of "GATTACA."
