I don't think Keith understood that if Dave told Scott/Holly they were safe he was just playing the game and probably didn't mean it.
I think he does.
He is just upset because Dave's playing the game put him in danger from Scott. He is being a big baby. He did the same thing, sucking up to Scott by ratting Dave out. They each wanted Scott to prefer them if Scott got the power.
