I thought Aiden's secret would turn out to be something else - and it kind of did but also not really. The revelation actually makes sense when you consider it's a magical world but I approached it from more mundane perspective.
Starting from the scene where MC's face meets his fist and the reaction of the... well, you know who... I was pretty sure he had some .... head... issues. I was surprised this wasn't the case (even if it sort of is).
I'm ready to guess this is what @MindOfFur intended, too!
