this is just a guess... but I think the King doesn't have 2 personalities, but there are really 2 of them (the other twin didn't die) it could be that Sigurd was lying about the died twin thing. Also Wilfred is probably the scary King?
and yep, just look through the comments and seems like others have the same guess ε=ε=(ノ≧∇≦)ノ
I haven't read the spoilers but it's obviously true. I wish Aida would find out soon and help his get over his dark past.
