I never understood why Odo and Quark disliked each other so much but this is what I like about Deep Space 9, seeing Quark and Odo butt heads. In a sense, Quark was known to be a selfish, greedy, often-perverted, con artist. I love Quark though. I remember the one episode where Odo and Quark's runabout crash-landed on a snowy planet, leaving them stranded until they could make it to a mountain peak without killing each other to send a distress signal. I maybe remembering that episode wrong but that's how i remember it. I liked how that episode about them being stranded on a snowy planet forced them to get along and put aside their differences. I also like the crush Quark had on Jadzia. Too bad for him though that she never liked him and Dukat killed her anyway at the end of Season 6. In the series finale, "What You Leave Behind" I laughed at the scene when Quark wanted Odo to talk to him one final time and say goodbye. But after Odo said he has nothing to say to him and left, Quark replied saying "That man loves me!" LOVED THAT! Of course Odo being a security personnel he can't engage in that type of behavior but i would've liked for Odo and Quark to fight. That would be a showdown i'd love to see.
