Margie loves her some Roxton. The man I love. Then again at the end, this little tender interaction between the two of them. Yeah, its been hinted at since the first episode, sometimes more overt than covert, but its always been lurking beneath the main storyline. I think it adds a bit of a spark to the show, but at one point its going to have to be resolved one way or another if the show goes on for long.
Courtships get tiresome after a few years.
I think the virginity thing is mostly played for laughter, as a way to poke fun at old myths in light of modern morality. Something big is going to happen between the two of them and soon. The only mystery here is about Roxton's emotions for her. While in recent episodes they have been pushing Margie's experience and saying outright that there is definately a love thing going on with her, they have not alluded to the depth of Roxton's feelings for her. I think Roxton is characterized as the stereotypical big game hunter, living for big adventures where a woman would slow him down.
