Charles is a trustworthy ex-drill sergeant. He is very friendly to all the children. When he isn't instructing those under him people describe him as a child at heart.
Sandra is an older woman who was the Principal's secretary. She is strict yet kind. She doesn't tolerate rude behavior and is very organised.
Jefferson was one of the teachers at the school so he knows the ins and out of the building very well. He is called a stiff and loves making up useless protocol. He means well.
Dominic is a ex-conman but tells everyone he was a train conductor. He is very selfish but hides it. He really doesn't care about the group except for his little daughter.
Already gave description of Ollie.
The end of mine and
