Lord John Roxton and Marguerite Krux are one of the best romantic couples you could ever have the joy to watch on screen. The chemistry between them is amazing and they spark off each other as soon as they enter a room. Both character's have difficulty expressing their true feelings and tend to use teasing, flirting, anger or sarcasm as a way of communicating instead. Both are the master/mistress of the hidden meaning and both are hopelessly in love with each other - and now, after three years, they've finally admitted it!

The attraction between them has been there from the first. Initially, Roxton was just interested in getting her into bed and even used the flimsy, 'body warmth' excuse on her when they had to sleep in a tent overnight. Don't get me wrong, Marguerite was more than willing to oblige but their eventual kiss was interrupted…and that premise has pretty much set the tone for the rest of the series. They ALWAYS get interrupted!

Any tender moments seem to be when they're either alone - where they indulge in a light teasing flirtation - or when they're in grave danger where their true feelings surface without thought. In front of the others, they've elevated bickering into an art form in which they seem to thrive on trying to outwit each other into betraying some feeling.

Although a man of the world, this is the first time Roxton has ever fallen truly in love. He has admitted to one person that he'd never met a woman that could break his heart until he met Marguerite. Another time, a trickster God tried to kill Marguerite and when Roxton saved her, the God told him that he should have just "let her go" to which Roxton replied with an emphatic, "Never!".

Marguerite, in turn, admitted to Roxton's 'dark half' that she loves him but has never told him. I think this is the first time she has experienced a true love also, even though she has been married at least once, possibly even four times. She does tend to mention her many 'husbands' to Roxton to get a reaction, usually jealousy, out of him.

Embarrassingly for Marguerite, Roxton found evidence of her secret desires when he discovered a piece of paper that she'd doodled on hidden in the bottom of her jewellery box. She'd drawn a picture of a fancy dress and had written, 'Lady Marguerite Roxton' in three different styles obviously trying out how she'd sign her name if they were married. When he showed her the paper, she looked shocked for a second but recovered remarkably well enough to tell him that she was merely thinking of his fortune. He snatched the paper back with a smile and told her he'd keep it anyway and then walked off whistling the wedding march - he knew she was lying.

The rest of the explorer's know how they feel about each other and can't understand why the two just don't admit their love.

Roxton suspects that Marguerite has been hurt badly in the past and thinks that's why she constantly fights him and her feelings. Naturally, he doesn't really know how to respond to Marguerite's hot and cold ways and tends to cover his hurt feelings with brusque comments and anger, sometimes resulting in them having a row of gigantic proportions. If he were more certain of her feelings then I think he'd be happy to express his own.

Unfortunately though, part of Marguerite's murky past was recently revealed and severely tested Roxton's love and trust for her.

Originally, the travellers thought that Marguerite's sole reason for coming to the plateau was for gems. However, it seems that she was forced to go in order to find the missing half of a pendant that, once joined, would be able to take the wearer anywhere they wished to go.

Roxton realises that she's been lying to them all from the beginning and is dreadfully hurt that she never told him of her own violition. Beginning to doubt that anything she's ever told him is the truth, he takes a step back in their relationship saying that he's only going to look out for Challenger, Veronica and himself as she's made it clear that it's not his place to care for her. He tells her that she's on her own, where he thinks she obviously wanted to be all along.

However, he eventually finds out that her prize for the missing piece, was a copy of her birth certificate which she desperately wants in order to find out who she is. Digesting this new information, he calms down and during an emotional talk, she hints that the reason she didn't take the amulet and leave was because of him. In return, he lets her know that he doesn't care who she is or what she's done and that he's still there for her - "Whenever you're ready, all your secrets will be safe with me."

And it's a good thing he said that because Marguerite sure does have a whole lot of them! It turns out that during the war she was a triple agent for England codenamed, 'Percival' (after the Arthurian knight) and Roxton, although not knowing who 'Percival' was at that time, volunteered to give up his military career and good name in order to take the fall for her so that her identity wasn't revealed.

This revelation strengthened their respect and love for each other therefore bringing them closer together when she realised how much he'd sacrificed, albeit unknowingly, for her.

Not long after the truth about their roles in the Great War came out, unable to hold back his feelings any longer, Roxton finally professed aloud what his actions had shown for many years. Unfortunately, Marguerite wasn't very receptive to his declaration and told him that he couldn't love her. Upset, he assured her that whatever secrets she still had weren't a problem but she replied that they were…for her.

Most recently, they explored a cave then got trapped after an explosion cut off their exit. With toxic gases in the air and oxygen running out, death was more a certainty than a possibility. They tried to dig themselves out but then Marguerite gave up and seemingly resigned herself to die. Furious at her attitude, Roxton completely lost his temper and they had a row of gigantic proportions ending in the hunter telling her that he was giving up on trying to win her as she wasn't worth his effort. He also added that she's a taker, she's cold, she's empty and goes on to vow that if they get out of their predicament alive then they're finished.

Once he calms down, he apologises and although she's hurt by what he's said, they begin to talk. She eventually reveals that she thinks he deserves someone better than her, but Roxton tells her that she deserves more than she allows herself to have. He declares his love for her again and, realising that she can't run away from her feelings any longer, she, at long last, says she loves him too.

Now their feelings are out in the open that doesn't necessarily mean things will run smooth for the couple. Marguerite being Marguerite, is very likely to go back on her feelings through fear of losing him - she hates showing any sort of vulnerability and Roxton would be her greatest weakness - she's not going to be happy about that.

Whatever happens though, at least they've finally taken the next step and you can be sure that with their ego's and pride the journey is going to be hard, fun, fiery and loving, but never dull!
