S7, E4: Mary Stuart Masterson guest-stars - When a 17-year-old high school student is brutally attacked by one of her classmates on campus, Detectives Stabler, (Christopher Meloni) Benson (Mariska Hargitay) and Fin (Ice-T) investigate Luke Breslin (guest-star Paul Wesley) the prime suspect. When asked about attacking his friend, Breslin becomes enraged and attacks Det. Fin (Ice-T) but when later questioned, he claims to have no memory of attacking anyone. Meanwhile, Stabler realizes that Breslin is the son of his former partner Pete Breslin (guest-star Noah Emmerich) and Detective Cragen (Dann Florek) suspends Stabler after he makes a number of unprofessional choices in trying to go easy on his friend's son. As the investigation continues, Stabler tries to help both Breslin and his son, but begins to lose control because of his own rage. Stabler turns to Dr. Rebecca Hendrix (guest-star Mary Stuart-Masterson) for help coping with his own anger issues. Richard Belzer, Diane Neal and B.D. Wong also star.
