I think that when Big Sister randomly drew circles on that unlucky Fallen Apostle, it might have already triggered quite serious consequences. Whether it was the initial black half-hour when captured, or the continuous daily strange accidents in prison afterwards, it left Carter mentally exhausted, the psychological shadow even more severe than that of the mysterious Prison Host. Now he is extremely allergic to anything circular, including the rerun of the London Olympics. It's unimaginable for him: just seeing the Olympic five-ring flag flash on the screen makes him jump. If he were to see a massive formation of people creating a circle with a radius of over a hundred meters at the opening ceremony, I can only imagine how agitated he would become. Anyway, I think if Big Sister drew such a large circle, it would indeed spell the end of Hollywood.
