The serial is obviously illogical! Haha. I also think that Laila probably is unaware of the fact that Nikhil has none of the things he orginally possessed! Also, I don't think she loves Nikhil...
If she did...do you think she'd do what she's doing? Maybe...if she's just selfish...who knows...
I mean, she did say that she originally came to help Kiran split up Anu and Dhruv...but then when she saw Nikhil again, her feelings came rushing back...so who knows...
