Well my life and what goes on in it really isn't your concern anymore
—David to Donna
Thicker Than Water is the 17th episode of Season 4 on FOX teen soap Beverly Hills, 90210.


David's addiction to stimulants spirals out of control and the result could cost him Erin's life.

Meanwhile, the gang heads to Big Bear for a weekend ski trip where Donna meets a cute ski bum named Chad, but her attraction to him is complicated by her still strong feelings for David.

Andrea gets a life-altering shock when she learns that she is pregnant.

With Suzanne out of town, Dylan spends the day with Erica teaching her how to surf, which takes a turn when Erica gets her first menstrual period which forces him to turn to Cindy for assistance.

Dylan also learns that Suzanne has been keeping secrets from him when Jim makes a background check of Suzanne on Dylan's behalf with her social security number and uncovers a hidden bank account containing $20,000 after Suzanne has previously told Dylan that she is broke.

When Dylan confronts Suzanne with the lie, Suzanne tells him that the money was only recently deposited into her account from a property insurance settlement after her home was destroyed by floods.

Dylan believes Suzanne and agrees to trust her from now on, but Jim continues to remain suspicious about her and her intentions for Dylan.
