WHY IS MARCUS FROM THE VOLTURI ALWAYS LOOKING SO BORED??AND WHAT HAPPEND TO HIS WIFE??read the text to find out
Once upon a time, a fairly young vampire (he had only been a vampire for a decade and a half) named Aro changed his young sister Didyme, who had just reached adulthood, into a vampire in order to add her to his growing coven. Aro always wanted power, and because he himself had a potent mind-reading gift, he hoped his biological sister would also be gifted in a way that would help him rise in the vampire world. It turned out that Didyme did have a gift; she carried with her an aura of happiness that affected everyone who came near her. Though it wasn't exactly what he had hoped for, Aro pondered the best ways he could use this gift. Meanwhile, Aro's most trusted partner, Marcus, fell in love with Didyme. This was not unusual; given the way she made people feel, lots of people fell in love with Didyme. The difference was that this time, Didyme fell in love herself. The two of them were tremendously happy. So happy, in fact that, after a while, they no longer cared that much about Aro's plans for domination. After a few centuries, Didyme and Marcus discussed going their own way. Of course, Aro was well aware of their intentions. He was not happy about it, but he pretended to give his blessing. Then he waited for an opportunity to act, and when he knew he would never be found out, he murdered his sister. After all, Marcus's gift was much more useful to him than hers had been. This is not to say that Aro did not truly love his sister; it's just that a key part of his personality is the ability to destroy even what he loves in order to further his ambitions. Marcus never found out that Aro was responsible for Didyme's death. He became an empty man. Aro used Chelsea's gift to keep Marcus loyal to the Volturi, though not even Chelsea's gift could make Marcus show any enthusiasm for it.
HOW DID BELLA GET PREGNANT? WAS THAT BIOLOGICALY POSSIBLE??
Vampires are physically similar enough to their human origins to pass as humans under some circumstances (like cloudy days). There are many basic differences. They appear to have skin like ours, albeit very fair skin. The skin serves the same general purpose of protecting the body. However, the cells that make up their skin are not pliant like our cells, they are hard and reflective like crystal. A fluid similar to the venom in their mouths works as a lubricant between the cells, which makes movement possible (note: this fluid is very flammable). A fluid similar to the same venom lubricates their eyes so that their eyes can move easily in their sockets. (However, they don't produce tears because tears exist to protect the eye from damage, and nothing is going to be able to scratch a vampire's eye.) The lubricant-venom in the eyes and skin is not able to infect a human the way saliva-venom can. Similarly, throughout the vampire's body are many versions of venom-based fluids that retain a marked resemblance to the fluid that was replaced, and function in much the same way and toward the same purpose. Though there is no venom replacement that works precisely like blood, many of the functions of blood are carried on in some form. Also, the nervous system runs in a slightly different but heightened way. Some involuntary reactions, like breathing, continue (in that specific example because vampires use the scents in the air much more than we do, rather than out of a need for oxygen). Other involuntary reactions, like blinking, don't exist because there is no purpose for them. The normal reactions of arousal are still present in vampires, made possible by venom-related fluids that cause tissues to react similarly as they do to an influx of blood. Like with vampire skin—which looks similar to human skin and has the same basic function—fluids closely related to seminal fluids still exist in male vampires, which carry genetic information and are capable of bonding with a human ovum. This was not a known fact in the vampire world (outside of Joham's personal experimenting) before Nessie, because it's nearly impossible for a vampire to be that near a human and not kill her.
