Casey married Peter. Now she couldn't help but wonder what would happen if she were with her ex boyfriend Tom. Marriage prevented her from doing this, so she asked her friend Emily to go find him and see if she could sleep with him, and then told Casey how things were. When Emily told Kathy that everything was great, their friendship was affected and Kathy's marriage was also affected. When Emily found out she was pregnant, things became even more complicated, and she wasn't sure if it was Tom or her boyfriend Elliott.
