In the next few days, the same thing happened several times. Sarah showed up when Billy's wives and kids weren't around and showed him some new tricks. At that point, even Billy, who tends to overlook small details, couldn't help but notice that something was off. That was way too weird... Besides, Sarah always showed up when the others were around. Almost as if she only had interest in the meetings of the group as a whole. While Billy taught her as many things as he did to others, she wasn't particularly more grateful or different than the others. So, he couldn't understand that...
"This isn't a coincidence… Sarah clearly is coming when the others are out," Billy thought. "Still, I doubt that she is always watching this place to know when that happens. Besides, they are leaving by themselves too often lately and this behavior started after they began to talk with Sarah… Are they working together? Is this some sort of plan that they came up with?"
