I've been a Twilight fan for over 10 years now, and there's one question (okay, there are a lot of questions, but bear with me) that I keep seeing about the series.
Yep. Everyone wants to know a) how Edward managed to bone Bella and b) how TF he actually knocked her up, given the rules Stephenie Meyer established about him basically being a walking, talking block of marble with no blood pumping through his veins.
If you're a stan from way back like me, you might already know the answer, but for those who don't – well, allow me to enlighten you.
First, here's a quick 101 on vampire biology from Meyer:
"Vampires are physically similar enough to their human origins to pass as humans under some circumstances (like cloudy days)...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)... 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."
You can see where this is headed...
Yep. Meyer says that vampires have a venom-like fluid that powers their boners.
Okay, so that's how Edward gets a boner. But WHAT ABOUT THE PREGNANCY, you ask?
Meyer has an answer for that too.
"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."
AND NOW YOU KNOW.
TL;DR Edward's jizz is venom.
This has been vampire sex ed with Stephenie Meyer and me.
