I’m guessing it’s that the main character’s baby is the “destined” lover of the character who was the second male lead. Alternately, it could be that the main character is a teenager courted by a man hundreds of years her senior, but that one tends to be less frowned upon in media.
Either way, I think Meyer would’ve come up with her drivel one way or another.
That goddamned movie made leaves look delicious and my child self did not appreciate the lesson in reality versus fantasy. ಠ_ಠ
