Major character who has only appeared on 1 page in the entire OOTS saga

[Rrmcklin]

My main issue with this is that it's kind of a pointless tease. The MitD will become an ally of the Order? Yeah, wow, big shock, that's only where his whole character arc has been headed for the last four books. Kinda weird to hint at something the whole audience already knew was coming, even as a joke.

This applies to a lot of the more popular guesses - Serini, "Orange Voice", probably others. Even if you could stretch a way for them to fit his wording, then the question becomes what's the point at "hinting" at something no one would be surprised by - no is surprised that Serini is still alive and in the story, and no one will be surprised if one of the mysterious voices at the end of the previous book will be important during the next half of the final book.

It just feels like people are more interested in being "right" than what the Giant actually said or the answer being interesting.
