Adrian's crush intensifies for Nick, but he quickly wises up and attempts to put her off, having begun a budding romance with coworker Amy (Jennifer Rubin). Adrian continues to boldly pursue him, sneaking into his apartment to rewrite his article which impresses his boss, and even going so far as to undress in his view while he is hiding in her closet. When Nick continues to rebuff her advances, Adrian's actions become destructive; she steals his favorite childhood photo, defaces a car he's restored, and erases his computer discs, yet he's unable to convince her parents of her guilt. Cheyenne (Amber Benson), a friend of Adrian's who tries to warn Nick about her, meets with an "accident" at the riding school they attend together. After Adrian spies on Nick in bed with Amy, she locks Amy in her darkroom and empties a wasps' nest into the vents, exploiting Amy's spheksophobia. Amy survives, and Nick, now convinced that Adrian is big trouble, attempts to find new lodging. However, Adrian accuses him of sexually assaulting her with "evidence" obtained from a used condom from Nick's trash, leading to the police arresting him. After Michael bails him out (and suspends him until trial), Cheyenne informs Nick that she knows he is innocent and that Adrian has an extensive history of obsessive behavior, citing a camp counselor named Rick who "accidentally" died by eating something poisonous. Cheyenne also informs Nick of a diary Adrian kept that can exonerate him.
