I went back home with the snake now human with me.
After a couple of hours of travelling I finally got back and asked my father in private.
"I done it so that your mother could love me. I was never like this, I was small and scrawny. I asked for god to change me better. Then I saw the snake come out of the bush and bite me, I felt a rush of energy and I found that I was more muscled and could become a hybrid of any snake, even prehistoric ones. I would keep this private from your girlfriend if I was you. Your mother will know as well once I've talked to her. OK?"
With the talk session over you go to your girlfriends place and you ________.
