Prince of Rascia wrote: Either King Leopold and Henry Sr. are brothers or Henry Sr. and Eva are brother and sister and Eva inherited her father's kingdom instead of her brother (maybe because king Xavier found out about some Cora's action and decided to disinherit the pair) That would explain why Cora was jealous on queen Eva and why she wanted the kingdom for herself (ups, for her daughter). From the episode credits, it looks like Eva  is Henry Sr.'s younger sister.

Prince of Rascia, I think your theory is spot on. King Xavier must have disowned Prince Henry, after discovering the truth about Cora.
