S3 E22: When Rebecca Tolliver (guest star Lois Smith) reports that her daughter Katie (guest star Andrea Fay Friedman), a 22-year-old woman with Down Syndrome, has been raped and as a result is now pregnant, Detectives Benson (Mariska Hargitay) and Stabler (Christopher Meloni) face the delicate task of determining if Katie was indeed sexually assaulted--or if her over-protective mother is in denial that her daughter has chosen to consummate her relationship with her boyfriend (guest star Badge Dale).
