My favorite thing about Body Parts (s4e24) is that Garak was obviously never going to kill Quark. He just decides to spend an afternoon in the holosuites demonstrating his terrifying skills for kicks. Then he solemnly promises Quark that he will definitely kill him very soon –
And you never see him again in that episode. He just goes to the Replimat and orders a spice pudding and eats it while reading poetry or something.
