Just finished the film, have a question for any book readers
How does Cassie find out that the Others have taken control of human bodies? How does Evan (or how would he I suppose, if he wasn't an other) know? Is this common knowledge somehow?
I know the military knows, and they told the group of adults at the refugee camp, but I assume there's some added details in the books about how lone individuals discern this information, or it's publicly disseminated in some way.
