Well, he did save Zadavia in "Acmegeddon part 2" and still I don't remeber hearing a word of thanks from Zadavia. Now if he sacrificed himself for her, that would change Zadavia's whole opinion on Duck.
Duck: What!? You mean I have to die to get her to at least notice my good qualities!?
Me: Well we don't know until WB might carry out the idea in an episode. You just have to be patient.
Duck: But doesn't she appreciate the fact I helped to release her from that table thing Optimatus was holding her in!? What an ungrateful-
That would be an episode i'd like to see. Everyone will pay for being big meanies to Duck!!! Mwahahaha I have noticed no one ever thanks duck for doing something right. Maybe it's impossible or something. Let me try it out... Me: Duck! Can you come here for a sec? Duck: What now? Me: Tha....tha.........tha................*struggling*tha................................. Me:Nope. Can't say it...

People just take advantage of Duck. But if Duck does save Zadavia again; instead of giving him the cold shoulder, Zadavia should start giving Duck the benefit of the doubt and try to at least make an effort to teach him the error of his ways.
