OK, Law & Order: Special Victims Unit fans: it's time to talk about Dominick "Sonny" Carisi, outsider detective turned Assistant District Attorney, and eternal almost-flame of Detective Amanda Rollins (Kelli Giddish). Season 21 has brought a lot of changes to the SVU squad, not least of which is Carisi's departure from the beloved NYPD and his subsequent crossover to what Finn (Ice-T) calls "the dark side": the District Attorney's office.
