Kelly's back! After a visiting Dylan, Kelly (Jennie Garth) can report he had "the same cheekbones, the same sideburns and the same commitment issues," so Kelly quickly refocused her attention on the latest drama, questioning Mr. Matthews and "student" Kimberly in an attempt to get to the bottom of their inappropriate relationship.
Naomi wasted no time plotting to spoil Annie's upcoming sweet 16, playing dumb and secretly inviting her old boyfriend from Kansas, the hunky Jason, to Beverly Hills as a surprise. At an awkward dinner with the whole gang, Ethan pulled Annie aside and asked her to tell Naomi and Jason that they're a couple. She squirmed her way out of it for now, but then Jason, who's staying with her brother Dixon (Tristan Wilds), kissed her while they're brushing their teeth in the bathroom later that night.
Meanwhile, Adrianna (Jessica Lowndes) was eager to do couple-y things with Navid (Michael Steger), but the student journalist was a little reluctant and said he's focusing on the big story of the day: the Mr. Matthews scandal. When Adrianna showed up at his house, his father, mother, aunts and uncles all welcome her to a family dinner, where they laugh, eat and generally have a good time until the rehab question comes up. Later, Adrianna said she adored the family -- despite the questioning -- and Navid admits the real reason for his reluctance: he's a virgin.
When Annie came clean to Ethan about the kiss the next day at school, they had a fight, he stormed off and it looked like Naomi had accomplished her mission. But Ethan showed up to the party (a little late) with a gift and they decided they're no longer hiding their relationship. To celebrate the decision, they start making out and Naomi, always snooping, spotted them through the window and pulled Jason over so he could see that his chance for reconciling with Annie was over.
Crying, Naomi manipulated Jason into an upstairs bedroom, where the pair started going at it, until Annie and Ethan, ready to announce they're a couple, discovered them. That was when Annie and Naomi had a screaming match over who slighted whom, and Annie stood up to the queen bee, dismissing her as a friend. Watch a clip.
Back in the adult world, Kelly stopped by to check in on Mr. Matthews, who was leaving his home with a suitcase. That's when Kimberly, who made her drug bust, showed up and Kelly realized that their relationship isn't inappropriate at all. Kelly promptly left and Mr. Matthews and Kimberly kissed like they were no longer undercover lovers.
Tell us: Was Annie right to be upset with Naomi for making out with Jason? What do you think of Kimberly and Mr. Matthews?
