What does Holly try to convince Butler and Juliet of concerning Artemis?

Artemis believes that he can avoid the time-stop thus avoiding the blue rinse. Holly knows that this is just not so, no one has ever done so before. Holly, like the other People, believes that avoiding the time-stop is completely impossible. Because Holly has just saved the lives of Butler and Juliet, she does not want to have them die in the blue rinse, so Holly attempts to save Butler and Juliet by calling out Artemis. She wants to know if he has told them about the blue rinse. Butler, however, has complete faith in Artemis.
