Blanch of Spain is King John’s niece and daughter to the King of Castile. She is an obedient girl who is willing to be used as a political pawn until war breaks out again and she finds her loyalties torn.
Somewhat naïve, she is shocked to discover that she cannot restore the peace her marriage was meant to seal by pleading. Once married, however, she follows custom and accompanies her husband, even though he is on his way to wage war on her uncle. She shows some evidence of a mocking tongue, though she may simply be a wide-eyed, admiring girl.
