What is the twist about the island's magic?

Key Magical Rules & The Twist

1. Memory Fade Mechanic — On Nakali, Jo and Raissa gradually lose memories: the longer they stay, the more their shared past slips away. The island’s magic isn’t just supernatural—it’s a force that literally erases connections. [Paraphrased from trailers and summaries]

2. Cost of Return — They learn that returning home from Nakali comes at a terrible price: forgetting their entire friendship. Leaving the island means erasing what defines their bond.

3. Nakali itself as a sentient selection — According to Jo’s grandmother in one trailer, you don’t find Nakali—“it finds you.” This implies Nakali may be more than a magical location: maybe it chooses people who are already drifting apart or vulnerable to forgetting.

4. Parallels to Eternal Sunshine — Many previews frame the film’s magic akin to Eternal Sunshine of the Spotless Mind: a place where forgetting becomes central to identity, not just adventure. The twist likely deepens this: the magic doesn’t just threaten memory—it reveals something about why forgetting happens.
