Diana and Martin's relationship...weir d?

Diana probably is really in love with Martin and Martin probably loves Diana and they just won't tell each other how they feel about each other. Stepsiblings should be able to data and become girlfriend and boyfriend since they both aren't blood related. They really do get irritated everytime one of them pays attention to a girl or guy which means that they really do have a love/hate romance relationship and deep down they really like each other and just won't edmit it.

I've heard them call each other bro and sis once or twice but I'm wasn't certain if that meant that they were actually related etc.

Which episode did they actually say that they were step-siblings.

English Language Anime: Dub it, don't pervert it.

It's based off an Italian comic that's been around for years. Very loosely based off it, I should say. Calling it one of the recent Western Anime shows is a little unfair seeing as how most of its inspiration comes from the comic series. Even if it has a semi-Anime style.

They're just watching out for each other. Although that French thing reminds me of Les cousins dangereux. Hehe :o)

It's vaguely based on a Bonelli's Italian comic Martin Mystere (black and white, 96 page monthly published from 1982, now it have 283 issue + about 60 special with more pages http://www.sergiobonellieditore.it/martin/archivio_arretrati/index.html ).

In the comics MM is an adult (he is born in the 1942 in NY), and Diana was the first his "girlfriend" for years and later his wife. Java is a Neandethal man who don't speak, that was rescued by MM during an expedition in Mongolia in the late 70 and from then they live together.

In the comic MM is a mix of Indy and Fox Mulder (but the charater was created in the 1976, with another name, 5 years before Indiana Jones movie and 17 years before X-Files), a writer and a TV conductor. Sometimes he work for secret base of the USA gov ("Altrove", in english "Elsewhere"), whose chiarman is Chris Tower, an ex CIA agent and schoolmate of MM. He have a special weapon, created 10.000 years ago by the muvian people, that paralyze animal and people.

There are 3 big plot in the continuity of the comics (spoiler for the comics inside):

- the Atlantis-Mu war, happened 10.000 years ago, with MM that discover information about this lost civilization.

- the MIB ("Uomini in Nero" in Italian), that try to destroy what MM found (like Mulder also MM discover that his father work for the MIB, but years before X-Files :) ).

- The Tata de Danan alien who in the past leave on the Earth six powerful alien artifact, the "hexagon", that created the gods of the various pantheon and varius mytical weapon and object (Excalibur, the Graal, etc).

it seems it's a problem of censorships, maybe the producers believed it wasn't good for someone if teenagers travelled all around the world if they were of opposite sexes...

It's a beautiful day, Vittorio Emanuele di Savoia is in jail.

Justice is done.

Well, you have to group up the relevant factors:

_Diana was never adopted by Mr. Mystery.
_They were never biologically related.
_Diana is just the other missing half of Martin - relevant, since Diana does what Martin doesn't and Martin does whatever Diana doesn't. They're the perfect match.
_Mr. Mystery can always divorce(?) - since we can tell that he's more of a workaholic than a good family guy.
_Diana can understand Martin perfectly, and vice versa with Martin.

We CANNOT call their love incest or condemn it - that's my general thought. And the above, I hope, can be as relevant as it could.
