The story is all set poised to go anywhere. Lots of possibilities! Here are some:
1. So Shyam is now a professional! Video, shideo and all. Good for him. That's his place. However, he is a very crafty villain and Arnav will soon have to realize about Shyam's intrusion. How he does that, he will have to put Anjali into the loop so she knows that her 'godly' husband is upto no good.
2. Where is Shyam getting all the money to conduct all these hi-fi operations? This costs money. Is Anjali supplying him with cash? Arnav should realize that too. And probably in due course he will.
3. After seeing how dangerous Shyam can get, one will not stop wondering how he will fight tooth and nail to jeopardize Arshi marriage. He could do anything: hurt Khushi, hurt Arnav, hurt someone from Gupta family. Whatever he does, I hope the tides turn against him in so far as RM is concerned. They're just one act (of his) away from knowing his 'asliyat'. But once that happens, he will officially be the villain of IPKKND.
4. This nagging issue of Arnav and Khushi's past. How will that come up? And in what way? After watching today's episode I did not get the feeling that Dadi knows anything about Khushi in such a way so as to implicate her mom with Arnav and Anjali's unfortunate past.
5. It is a fact that we are all waiting to see Arnav-Khushi's marriage in a happy, convivial ambience. Now with Shyam in the picture, there is probably a suggestion that he will jeopardize it. We do not want to dampen our fun here, at any cost. But can never say.
