Carol's Immunity
Why Carol — and only twelve others — never joined.
Updated through S1
Carol, like the other twelve, was simply unaffected when the signal's code rewrote everyone else. No shared trait among the thirteen has been identified, and the show has offered no biological or metaphysical explanation.
What's confirmed in canon
S1Carol is established as one of thirteen immune, with no explanation given for why.
Where the community lands
Carol's immunity is bound up with the show's theme: is her resistance to bliss physical, or is "the most miserable person on Earth" immune to a virus of contentment for reasons that are almost poetic? The answer is one of Season 2's biggest promises.
