User: A very special island is inhabited only by knights and knaves. Knights always tell the truth, and knaves always lie. You meet 3 inhabitants: Samuel, Ella, and Logan. Samuel commented, "Logan is a knight if and only if Logan is a knave". Ella remarked, "Ella is a knight". In Logan's words: "If Logan is a knight then Ella is a knave". 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>.

Samuel cannot be a knight, because this would contradict the claim of their own that Logan is a knight if and only if Logan is a knave.
 Assume Samuel is a knave.  No contradiction is found in their false claim that Logan is a knight if and only if Logan is a knave.
 Assume Logan is a knight.  No contradiction is found in their claim that If Logan is a knight then Ella is a knave.
 Ella cannot be a knight, because this would contradict the claim of Logan that If Logan is a knight then Ella is a knave.
 Assume Ella is a knave.  No contradiction is found in their false claim that Ella is a knight.
 Therefore, (1) Samuel is a knave
 (2) Ella is a knave
 (3) Logan is a knight
