Don Carlos, a very attractive and eligible Spanish Prince. The son of a king, and on the prowl for his own Queen to gain power and wealth sooner. He is very charming and well educated and appears genuine.
Don Carlos is nothing like the man expected of him. He is charming, playful, and he enjoys adventures. He wants to play a game where he is chased by Mary through the woods. And, he wants Mary to whip him, sexually.
Don Carlos sailed from Spain specifically to meet her majesty Queen Elizabeth. He had written to her already, seeking an audience with the new Queen. Upon meeting her, he revealed though they were a good match politically, he wanted her as his bride because he was tired of waiting for his father, King Philip to die. He wanted to be a King. Elizabeth said he would consider his request. 
Days later, Elizabeth told him she was interested in his marriage proposal. However, a rumor had started circulating about her and Don Carlos requested she lift her skirt to prove her female status. Elizabeth refused, insulted at his bold and very rude accusation and sent him on his way, thus ending their brief relationship. 
Don Carlos left England for Austria and was courting Archduchess Anna of Austria for a few weeks. Things were going well until she found out about his sexual fetish. They both viewed his fetish, and her discomfort with it as a deal breaker and ended their relationship.   After, he made his way to France to court the widowed Queen Mary of Scotland.
