S15, E13: Sixteen year-old Avery Capshaw's (guest star Fiona Robert) parents report her kidnapped, and the SVU finds signs of a party turned violent. Her boyfriend, Manny Montero (Juan Castano), is a scholarship student from the Projects, and though his family swears he's on the right track, Amaro (Danny Pino) suspects he's involved with a dangerous gang. When Manny refuses to talk, the cops are forced to arrest him, but the violence only escalates. Meanwhile, Benson (Mariska Hargitay) is sworn in as the SVU's new sergeant.
