Could The Fireflies Really Make A Cure?
Short Answer
Season 1 treats the Fireflies' cure plan as sincere but uncertain; the real conflict is that Ellie is not allowed to decide whether to risk her life for it.
Why It Matters
This question matters because it connects Fireflies, Vaccine Hope, Ellie Williams to the larger conflict rather than treating the moment as a twist in isolation.
What It Changes
The answer reshapes how viewers read the surrounding episodes: character choices, world rules, and the ending all become clearer once this point is understood.
