Path Two, Karen's Story.

Karen goes out on a date with Tom as soon as she knows she is pregnant and knows you aren't going to have a relationship with her. He is rich and she knows he likes her. She gets him blacked out drunk on that first date. She has boy girl twins and she passes them off as Tom's. The twins both have their Mom's red hair. Her mom and step-dad don't like that she is a pregnant high school senior, but relax when they see her boyfriend is rich. Tom settles down with the upcoming parenthood and quits drinking and becomes a model citizen. Mysteriously the couple have no other children.
