Beverly Hills, 90210 - Season 5 Episode 23 Love Hurts

Lenny is released, as he has an alibi and the victim (an acquaintance) clears him. He confesses to David that he served time for sexual assault; he may have taken part in a rape while wandering the streets in a drunken stupor during his tour in the gulf. The outraged students try to run Lenny off campus, and Brandon agrees to help him transfer to another school. Valerie convinces Donna that David is to blame for Ray's departure. David and Donna get into a screaming match. Lenny reveals that Garrett Slan, a CU cafeteria worker, also spent time in a military prison. Brandon warns Clare that Garrett may be fixated on her, but he has moved on to Donna. Garrett breaks into the beach apartment, holds Donna at knifepoint, and tries to rape her. David interrupts as he comes over to apologize to Donna. She lets him know that something is amiss by calling him ""Dave,"" and he bursts in and hits Garrett in the head with a baseball bat.
