Mason said, "Scarlett is a knave." Samuel was heard saying, "If Henry is a knight then Riley is a knight". According to Henry, "Samuel is a knight and Samuel is a knave". In a statement by Scarlett: "Mason is a knight and Riley is a knight". In a statement by Riley: "Scarlett is a knight". So who is a knight and who is a knave? Show your work in <think> </think> tags.
