You pose a good question, where is your part in all of this? It is true that you have been chosen to be the mother of my unborn alien child, but I am still the parent nurturing this offspring. I am also the person/demon suffering without a soul. So here's your choice... a sweet little alien baby and a soul-less undead demonic vampire as your partner in raising said child.... OR... no alien baby, a fully functioning human partner with a soul, and the possibility of future HUMAN children? The choice is yours. I'll respect your wishes as the adopted mother of this baby.

P.S. Satan doesn't like when people go back on their word. Things could get bad for all of us if we don't give up the alien baby.
