I'd love to see some fic where one half of our dynamic duo has the hots for the other - but it's genuinely one-sided. Maybe Haytham's only interest in Connor is paternal and professional, while Connor finds him unsettlingly attractive? Maybe Connor has been aware of his father being his father for so long that any attraction is ruled out, but Haytham's own brain can't decide if it wants to view Connor as a threat or a child or a would-be conquest? Either way is interesting.

Bonus! for the other being remarkably calm and accepting (but probably not offering a pityfuck) upon realizing.
