Vivien is having a very bad week, her boyfriend abandons her, she has hot steamy sex with a man who looks like her ex, she loses her job, and she ends up pregnant.
Ross, falls for Vivien and then finds out he looks just like the ex and it throws him for a curve. Worse, he finds out she is pregnant with his child while in the middle of his engagement party to another woman.
Fast paced and exciting. Very nice.
