I have a theory... (no spoilers)
I think the tea they drunk have drug in it.
And the ones who put it were Ryan and Christoph - They used it to test Kyon. It was stated at some point that if the person that touched the drug last didn't him to become a zero or wouldn't want him to die the mutation stops and the served him the tea was Kyon.
i think it just christoph and ryan has his doubt about him
I'm not crying, you crying!! ╥﹏╥
