Knight, Knave and Spy Riddles

"Since A is the knight and he always tells the truth, C is the spy. It follows that B is the knave by process of elimination." You mean C is knave coz A says 'C is a knave' which holds true tok coz C says 'i am spy' which is a lie, and by process of elimination B is spy. Edit: deymn emo guy
