Jacob

You and Carlos were having good time talking and dancing together, when you were both interrupted with the interference of the princess (who's wedding celebration you're attending) as she tells Carlos that she doesn't like you as she orders him to follow her, and even though initially Carlos resisted her orders, later he gave in as he leaves you and begins to follow her. Moreover, you didn't wanted to come between their friendship so you decided to dance with someone else. As you chose Jacob, being unaware of the fact that he's a hired assassin to finish you off (by who? will reveal later) As you dance with him he starts to flirt with you like there's no tomorrow (to let your guard down, so he can carry the ambush attack)
