A conversation between User and Assistant. The user asks a question, and the Assistant solves it. The assistant first thinks about the reasoning process in the mind and then provides the user with the answer.
User: A very special island is inhabited only by knights and knaves. Knights always tell the truth, and knaves always lie. You meet 5 inhabitants: Henry, Samuel, William, Mia, and Scarlett. Henry expressed that If Henry is a knight then Samuel is a knave. "If Henry is a knight then Henry is a knave," Samuel declared. "Henry is not a knight," William claimed. As Mia put it, "Mia is a knight if and only if Scarlett is a knave". Scarlett said that If Henry is a knight then Mia is a knight. So who is a knight and who is a knave? Show your work in <think> </think> tags. And return the final answer in <answer> </answer> tags, for example <answer> (1) Zoey is a knight
(2) Oliver is a knight
(3)... </answer>.
Assistant: Let me solve this step by step.

Assume Henry is a knight.  No contradiction is found in their claim that If Henry is a knight then Samuel is a knave.
 Samuel cannot be a knight, because this would contradict the claim of Henry that If Henry is a knight then Samuel is a knave.
 Assume Samuel is a knave.  No contradiction is found in their false claim that If Henry is a knight then Henry is a knave.
 William cannot be a knight, because this would contradict the claim of their own that Henry is not a knight.
 Assume William is a knave.  No contradiction is found in their false claim that Henry is not a knight.
 Assume Mia is a knight.  No contradiction is found in their claim that Mia is a knight if and only if Scarlett is a knave.
 Scarlett cannot be a knight, because this would contradict the claim of Mia that Mia is a knight if and only if Scarlett is a knave.
 Scarlett cannot be a knave, because this would contradict the false claim of their own that If Henry is a knight then Mia is a knight.
 We have exhausted all possibilities for Scarlett, so let us go back and reconsider Mia.
 Assume Mia is a knave.  No contradiction is found in their false claim that Mia is a knight if and only if Scarlett is a knave.
 Scarlett cannot be a knight, because this would contradict the false claim of Mia that Mia is a knight if and only if Scarlett is a knave.
 Assume Scarlett is a knave.  No contradiction is found in their false claim that If Henry is a knight then Mia is a knight.
 Therefore, (1) Henry is a knight
