I just made this account to ask whether it's a mistake in just my books or in all the books, because I remember when I read it recently, in book 4 (Summer Night) McCoy called the Merlin Alfred, but in every book after that it says his name is Arthur. And then I noticed in this timeline he was also referred to as Alfred, so my question is what's his name, and whether anyone else noticed this or if it's just my version of the books? (Bear in mind that they're in e-book format)
