The presence of Coraline as their flatmate has improved Sara and Bryce's friendship as though she was the missing piece of the puzzle, the one that bridges the gap. Fortunately for Sara, Bryce has stopped bringing the sensitive topic up.
Unlike the ignorant Sara, Bryce was fully aware Coraline is a vampire. He is certain that she is a vampire because of the accommodation law set by KEI. The general law that every member of KEI knew to being a resident in the accommodation provided by KEI is the two girls and one boy ratio per flat - Coraline has proven to complete their initially lack of member as stated.
However, there was another rule that only vampires knew and only a handful of the humans are in the know. Bryce was one of them and he would know better than to let the cat out of the bag. Exposing this piece of information would only spell trouble for him and he would not want to find out what that trouble would be.
