It wasn't Zoey's fault. She never liked Dustin but seeing him the other girls made her feel something she had never felt before. JEALOUSY.
Zoey couldn't stand the thought of Dustin being with anyone else but she sure as hell didn't want to date him. The idea disgusted her.

Dustin was desperately in love with Zoey, (or she liked to think so) but she only thought of him only as a good friend. Maybe best friend. Maybe even brother. If she had a pound for every time he asked her out. Well, she's still have to same amount of money. But if she had a penny for every time he flirted with her? Probably about 50p.

Dustin however, Didn't want to date Zoey. Never. NOT EVER. He though of her only as a friend. Maybe a best friend. Maybe even a sister. And if he a pound for every time she asked him out? Well, he'd be a millionaire.
