In my favorite episode, Duet, did anyone notice a Hannibal Lecter/Clarice Starling vibe between "Gul Darheel" and Kira? You have an imprisoned, murderous-yet-brilliant psychopath and an already traumatized young woman with whom he mind-fucks when she visited his cell, leaving the female protagonist feeling bewildered. With what I think is the finest acting performance in all of DS9 - Yulin Harris (or was it Harris Yulin?) playing this complex, extravagant monster to the hilt!
