The Director had at first, given Cass a rather strange look at his confident words. But he was proven that his mentality was correct when it came time for the kids to grab their candy. 

Sam had managed them perfectly, even in conjunction with Lady Ava. The kids were well-behaved, and Cass felt a little bit bitter that they were treating Lady Ava so well, but hadn't treated Cass the same way.
