I think so, I mean considering her being half vampire, and Jake being a werewolf. The Baby would be either just a half. au the baby will be a human that can turn into a werewolf when the time came. au The Baby would be a half human, Half vampire, Half werewolf. It all depends I think, but I think the most probable answer would be a half human, Half vampire, Half werewolf. Hope I helped. :)
Having read the Guide and seen Jacob's family mti I'm inclined to say that they will have twins. Other than that, who can say? I personally think one will be wolfish and one will have zaidi vampire-like characteristics. I don't really think they could have both at the same time.
As much as I wish she can, I highly doubt that Nessie can get pregnant. She will stop aging when her body is fully matured (around the actual age of 4). In Breaking Dawn, Bella explained how a woman has to age to have a monthly cycle, and, of course, wewe have to have a period to get pregnant. I'm not trying to be too technical, but I doubt she can.
No. I do not think so but it would be awesome! We shall wait and see! She might go back with Jacob and Jacob will help raise Nessie and then she might have another kid but it might me half vampire and werewolf! That would be so awesome! Thank wewe for asking!
