This week Vikram sure showed very good judgment and reasoning; just as good as Kunal.
As viewers we all know that current mess SINAL are in is started from the point Rohit interfered with Vikram's business and try to frame Vikram in wrong case. That time Vikram made a mistake by asking Siddhi to hide it from Kunal. Siddhi sure made huge mistake by agreeing and later trying to resolve this issue on her own. I doubt that Siddhi is going to realize where this mess began. Given her current state of mind, (fear and vulnerability about Kunal) she is going to continue making same mistakes. I believe she has over active protective sense in general, but especially when it comes to Kunal given her too much love for him; it compromises her judgment. She sure trust and respects him, but current circumstances combined with her too much love, she is bound to be desperate, not to mention stupid. We do not know when CVs plan to provide her with epiphany that her decision making is not always sound. Our hope is current track gives her that.
But Vikram has realized it. As he talked to Raveena, this mess began from with the case against him. He made mistake by hiding it from Kunal and Siddhi agreed. That led Siddhi to go after Rohit on her own and a fight between SINAL. That fight was reason for the accident. Now Thakral is using whatever Siddhi did for Veera to argue for murder. As Vikram said, be it unintentionally, Veera does create problems for SINAL and also one factor that is responsible for this whole mess.
So dear Vikram, now that you have figured out this arrangement, please realize it would be wise to be honest with Kunal and inform him everything you know. Vikram also realizes that Siddhi, someone who risk a lot for others(Raveena) is obviously going to risk it all for Kunal. So unliek your dumbo wife, do the right thing and talk to Kunal before SINAL gets in more trouble.
