How does Dev expect Kaajal to trust him when he himself didn't trust Kaajal by telling him he is Dev not Raju. I mean he put on an act in front of Kaajal, false papers for Kaajals benifit and time and time again when Kaajal told not asked if he was dev he plain outright lied. So with what face can he accuse Kaajjal of not trusting, when he himself doesn't trust he enough. I mean if he was putting on this act to catch KA, then why wasn't Kaajal allowed to know. I mean she was supposed to hide the fact he is Raju to them anyways, it all doesn't make sense.
As I have wrote in the DOW section, Kaajjal and Karan is a whole new level to illogical on the script writers part. It's just silly how the story is taking a turn...
