(view spoiler)[When Sammy is in the bus they use a metal disc thing which glowed green or read to 'check fever'. There has to be more to it! What was it all about? And what happened to the girl who got a green result and was taken to the hospital( whom Sammy befriended)? can anybody explain? (hide spoiler)]
This answer contains spoilers… (view spoiler)[When Sammy glowed red it meant that he was healthy, in my opinion it was a way to decipher which humans are more controllable in a sense. The girl glowed green for unclean so they are saying that she was sick but that isn't the case because they have other plans for her and kids like her. In the second Book, The Infinite Sea, you discover what really happened to this girl and to other kids. (hide spoiler)]
Cailyn M The girl on the bus, in my opinion, was probably killed as they are trying to create an army of the strongest humans. Personally, I think they thought she would be a threat as she was very cautious and alert so they killed her for being a problem.
