108 (Nicki's POV) - S1.E8

Nikki is still seeing Gary behind Louise's back, but when she meets an attractive man at the coffee place she doesn't think twice before posing as a model to go out with him and blow her friends off. He takes her to a fancy dinner and later to a hotel room where they spend the night together. The next morning the man is gone - and so is her credit card. She is left with a £600 debt and has nobody to call for help, except Alex. Poor Alex has to call Dan to save Nikki, which eliminates what could have been a last chance for them to get back together. Nikki realizes the mistake she made, but leave her alone for two seconds and she'll be jumping right into another man's bed, proving she still hasn't changed at all.
