She means Vivek Oberoi is out to tarnish the image of Ash by giving interviews about how she dumped him and all. She did not mean "Man on a mission" in a positive way. That's y Shweta was saying "Mommm"
i Completely agree with ur thoughts...Which mother-in law will like their bahu's ex bf...Anywsy's that was mean of Jaya Bachan to say that....i mean the mistake isn't done by Viviek alone and Ash was in this relationship equally and she broke up with him without any reason..or may be he was not that successful..:)
