Before the day of the full moon, Gary had already informed Kai and Olivia that he was next to a 100% sure that as long as they starved themselves, and therefore kept their Energy low enough, they shouldn’t be able to transform during the full moon.
Taking their leader’s words with a grain of salt, Kai had come up with some theories of his own on how to deal with that starvation, so he had suggested they test those out to find out more about their condition.
After drawing straws, Olivia had ended up being the one who had been forbidden from eating enough 72 hours before the full moon, making her by far the hungriest. Although she had been complaining a lot, the Lady Boss had acted fine when the clock had hit midnight and only towards the end had she displayed signs of aggression.
Gary was the one who should stop eating meat starting one day before the full moon, and he had even used Claw Drain a few times before midnight to get his Energy down.
