Single-motherhood is a plague to modern day society. Feminism is cancer. This is traumatic and shameful even to watch. She doesn't even have the courtesy of being gentle with her pregnancy. Sure enough, someone different from the fathers of the boy and the pregnancy still tapping that even while pregnant.
The boy should just go on a mission of looking for his father, maybe his father's guidance can help him, otherwise he can be consumed with rage and turn into a monster. I don't want to imagine how traumatising this can be, without a father figure and the only person to look up to as a mother is a pregnant harlot
