Jackie Cook

Siren /Si"ren/ n. An enticing, dangerous woman.

Fresh off the plane from New York, Jackie arrives in the oceanside town of Neptune to make her own waves. When she's not antagonizing her strained relationship with her father, Terrence, she's insulting the people who prepare her food. Smart move? Not so much.

She catches Wallace's eye on her first day at Neptune High, and he uses his newly developed detective skills to help her discover who hit her father's Porsche. She's not a Jane Austen fan, but her inflated sense of self gives her the pride to brag about her exciting life in Manhattan and a prejudice against certain personality traits like not toying with the feelings of a guy who's totally into her.

But give the girl credit for having the heart to one-up Veronica. Jackie arranges for her to get punk'd on national, er, local cable-access television. And she TiVos episodes of Cupid, so she can't be all bad. Never mind her penchant for fake psychics and mood-altering drugs that make her come on to Logan.

She redeems herself by helping Wallace take down the men who tried to take him down, and she hopes it will put her back in his good graces. But Wallace lets her know, in that cheesy-grin way of his, that he only has room for one "pretty and fun but morally ambiguous" BFF in his life.

Maybe her diva-tude will change if her father goes to jail and causes her to join Neptune's ever-growing club of rich but orphaned 09ers. In the meantime, allegations of him being connected to the bus crash cause Jackie to be so unpopular at school that she makes Veronica look like Homecoming Queen. Her new outcast status causes a slow thaw between them, and they just might be on their way to becoming friends. Together with Wallace, they'd make a great crime-fighting trio.
