Welcome back, 90210 fans. Here's a recap for the latest episode of the show, which picked up, aptly, following winter break at West Beverly...

We'll start with Dixon's story line: this stud continues to befriend Christina, much to the chagrin of Silver. Dixon even gets invited to Christina's father's fancy house for a music-based barbecue. He's a producer or record label executive of some sort and Christina has been introducing Dixon to new music; black artists, to be specific.

Silly Dixon initially lies to Silver about attending the party, but soon his fears are assuaged: Christina says she's a bisexual (and is dating a singer at the shindig, no less) and doesn't look at Dixon romantically. He quickly calls Silver, invites her over, apologizes in person for lying and explains that it was simply refreshing to be affiliated with black culture. Silver's forgiveness is not all Dixon earns, though:

Christina's father has him sing Amazing Grace for all the guests.

Meanwhile, Adrianna visits a doctor with Kelly and Brenda because a guy she used to sleep with comes up HIV-positive. Fortunately, she's in the clear, but she receives different bad news: Adrianna is pregnant. And she doesn't even know who the father is because she slept with so many guys while using drugs.

This story line also leads to a revelation from Brenda: she tells Kelly tha she isn't able to have children. She is, however, newly motivated to adopt. (Might she end up with Adrianna's child?)

The main focus of the show, of course, was Sean, the shady, supposed son of Harry and Tracy. Annie and Debbie thought something was fishy about him, and for good reason: he told everyone that he needed money - $200,000! - because his late father had gotten into severe gambling debt. Now, the men his dad owed money to were coming after Sean.

While Tracy and Harry were trying to determine a way to come up with the cash, Annie snagged Sean's phone. She saw the last five numbers he dialed were the very same private investigator that had found Sean; were they working together to steal money from the Wilsons?!?

Due to pressure from his family, Harry asked Sean to submit to a paternity test. But when everyone awoke the morning Sean was scheduled to take it, he had vanished!

Harry finally realizes that Sean was never his son and was scheming to take what wasn't his. He takes it pretty hard, but not as hard as Naomi.

Turns out Sean stopped at the Clark's house before leaving and Naomi's mom gave him the money. Now, she blames Annie for taking away her step-brother and for costing her family such a large amount of money.
