My take on this statement is that both father daughter duo have conveniently forgottten what all Armaan did for them. Today they are standing in Sanjivani because of him otherwise their dream project would have been crumbled down long ago if Amy wasn't there....hypocrites.
Even now Shashank is asking Amy to do more for so called Gupta family...i wish there should be a warning sign outside Gupta Villa...."Beware of Us". Horrible family.
