Ok, short version!
Magic is real, My dad is a Warlock and he found out that you knocked me up!
So that’s why I look like this?
No, That’s a side effect. Since you didn’t want to drive me out of state to end the pregnancy, he insists that YOU carry it to term
WHAT?
Sorry Jeff, but he felt that, since you felt so strongly about protecting the life of the unborn, you were best suited to make sure it remains healthy and happy.
Happy?
Well yes, being pro-life doesn’t end at birth Jeff, My dad expects you to be a nurturing and supportive mother to the baby too.
But that’s 18 years!
No, It’s a lifetime. He will be watching too, if you ever mistreat the child, he has worse transformations at his disposal
