Here’s a place to post about romances which were never exactly written in the series. I’ll start out:
Gilligan’s Island,
The Skipper and Gilligan:
Pretty obvious here. Pet names (lil buddy), violent outbreaks (possibly due to a S&M type relationship), and here’s what makes it all obvious: Gilligan’s (possibly subconcious) foiling of most attempts to get off the island. He’s probably afraid that once they get back to civilization, the Skipper will break off the relationship for fear of being viewed in a bad light in proper society.
