I don't really like the final book anyway, and Renesmee is the main reason. Not because I don't like her, but because she should not exist. You would think that Stephenie Meyer-having had three kids-would know how it works. I Edward has no bodily fluids, how could he possibly impregnate Bella? I can think of no way except, "Oh yeah...Uh, he has no bodily fluids except that...Yeah..."
One person had the theory that he could only impregnate someone once, having had "that" stored up through the years. One: in her story there is one vampire who had at least three children, so that's out. Two: it would not still be there. It would have dried up. Three: it would not be there in the first place.
So, I can get no explanation thus far, other than, "Stephenie didn't think this through that much."
Any suggestions?
