Martin Short as a guest star is one of the most genius moments in Law & Order: SVU history, period. When an 18-year-old woman is kidnapped and raped, psychic Sebastian Ballentine (Short) inserts himself in the investigation and claims he has key information that can help. All of his advice and tips start to become very specific and then the SVU team begins to question whether or not he's involved. This is one that gets under your skin and doesn't leave.
