Hey there,

Your question states: What does Tom Canty do that makes some people in the palace suspect that something is wrong with Prince Edward?

What Tom would do is he would pretend that he would not be the prince and that he would also pretend that he wouldn't know how in the world is the king, which is his father. That's one thing that Tom Canty would do in the palace that would make people think that something is wrong.

Your correct answer is the following: He insists that he is not the prince, and he fails to recognize Prince Edward's father, the King.
