i am confident that its neel who is doing all this....here is my theory
1.y did he come back all of sudden
2.how did he know that there is a show by saloni in delhi
3. y is he staying in saloni's house when he wants to go away from all this?
4. y is he becoming close to Nahar?
5. y did he make it a surprise visit?
6. y did he suggest to go to wish her before the performance?
7. y did he stop nahar from going close to that lady?
all this is cos he did notice that Yug was going very slow...and many think we not possible by him what he could do it him self....and he is also very clever enough that he did not come openly with Yug ....but he made another person sit in front of Yug....and he took the game rite in his hand....now with all this the ball is in ur court...what do u guys think.....
