Why is Drayven's father such a jerk to him again? Just because Draymen isn't a stereotypical nor cliche royal like his old man or something like that?
There are a few reasons (not very good ones) as to why Alphonse does what he does, but it isn't without reason. I can't get into them yet because of spoilers - so you'll have to keep reading to find out!
just gonna say now, it's Kings like these that get usurped by their sons. the way Drayven's Father treats him is just asking for Drayven to stab in the back
Hahaha.. yeah, foreshadowing!
