Might be a result of Kushal's childish temper tantrum about Gauahar, if she loves him, won't talk to Ajaz.Armaan probably doesn't know about this (since he's probably counting all the money that he's going to have to pay out to his lawyers in his head ) but if he did, he'd be jealous. He told Tanisha not to talk to Andy but she never listened to him!! And Gauahar (silly her!!) actually listened to Kushal's jealous frustrated request!!
