It was a brilliant episode, a very worthy sequel to the equally excellent House of Quark. I thought the scene with Quark fighting using the control thingie with Worf was brilliant, only at the end did I remember no-one was actually being controlled; Armin Shimerman was just acting his ass off. I also liked the old Klingon quite a lot, and how, when Worf was trying to woo Grilka, he didn't go the standard shouty Klingon "DISHONOURABLE DOG, FIGHT ME TO THE DEATH!!!!" thing, but just took Worf aside and explained she was not interested like a normal person. And Worf and Jadzia playing Cyrano for Quark... Well, overall this episode was just a delight.
