In other news, reading a popular YA novel and having some doubts as to whether it's possible to foreshadow the identity of a character who has amnesia without telegraphing said identity. So you have a young man who doesn't know who he is and has only brief flashes of memory from his childhood? And you also have the oh-so-brief mention of a prince who *mysteriously died as a child*? Nice try.
[If he turns out not to be the prince, I will issue an apology. Also, pigs will take to the skies and the mythical netherworld will experience a cold snap.]
