Hey guys I've noticed a few things????????

1) When Simran had Raghu's phone with her, she recieved a text message and was really shocked and then said, "Main Tumhe Ab Nahin Choroongi" and the next scene Raunak gets arressted . What got me thinking in this scene, is that Simran, Arya and Drone were absolutely certain that Raunak was Vansh's killer, so why was Simran shocked at the txt that she received on Raghu's phone. 

2) Why is Ishita hell bent on splitting up members of K.Mansion and also for her and Aditya to join with Bikram and GK.

3) Before Raghu was murdered, why was Bikram shown to have the rope with him.

Below are my theories of what I think will happen????

A) Raunak is the killer.

B) If Rauank is the killer, no way do i reckon that he did all of this on his own, there has to be a bigger mastermind, behind all this. To me this doesn't seem like the work of Raunak.

C) What if Simran and Raunak know who the killer is and are putting up an act, to unveil the killer....?????

D) Or what if Arindham and Debu are alive and are being held hostage and Raunak is being forced to say that he's the killer, cause Arindham is his real father after all.....???????

E) Or what if Arindham is the killer, and Raunak knows this and has taken the blame on himself, thinking that Arindham will reappear on the screen and confess....????? - Test fatherly love.

F) Or what if he's doing the same for Ishita or someone from K.Mansion, unveil them, cause he knows that no-one believes him and think that he's Vansh's killer. If he's doing this then, this in a way can be good, cause the killer will now be careless and leave evidence, making the unveiling a lot easier for him and Simran?

What do you guys think?

Which theory is the best
