hey guys can you help me!!!!!!!

Did Raghu ever mention that he actually saw the killer, when he or she contacted him, in the first place? If not, then this could mean that Raunak is not the killer, cause what if the killer contacted him over phone or sent someone, but gave Raunak's name.

Hence Raghu then tries finding out who he is Raunak and actually sees the actual Raunak. And assumes it is him, therefore taking his name when he died.

Cause when Raghu was murdered, it was Bikram who bought the rope with him, so my guess is that the killer is more than one person.

actually,raunak said to raghu on that phone that he is raunak khandelwal calling!!!! and raunak voice was also there !!!it might be this reason!!!!i think so (NOT SURE)

If Raghu only contacted Raunak over the phone, then I still say that Raunak is not the killer, cause don't forget, if GK can get someone to speak in Simran's voice, saying that she is Vansh's old girlfriend, Then why can't there be a male person who can fake their voice.

ya it cud be!!! yaar par raunak ne simran ko bata diya hai ki vansh ka katill raunak hi hai !!! aur i think woh sach bole raha hai !!! now wat can i say !!!
