My take -if a chip has been injected

Two things may happen. If it's just a chip or tracking device, then Aryamann wants to know movement of Manik. What is he doing? Where is he going? Then maybe after getting a suitable chance, he may attack Manik without leaving any proof or putting blames on someone other. On other hand if he is joining hands with Nyonika against Nandini, he may reach every place where Nandini is and behave like in a way that it will create false impression in Manik's mind about Nandini regarding Aryamaan Nandini relation. But this won't be successful.

Second if it is a chip through which we can hear or visualise anything, then it may somewhere helpful to manan. Aryamaan may know the real innocent Manik. But there is little chance of it. Because cvs are very much interested in villains. Otherwise he will keep some intimate picture of manan and use it like a mms scandal. But this is also tiny possibility. Main aim maybe the information regarding album thing, he may copy fab5 performance and ditch them on day of competition. After that he may put blame on Nandini that knowing everything she remained silent. If something bad will happen with fab5 due to hidden things of Nandini, Manik won't able to forgive Nandini easily. I am going with this point strongly. Because Manik will lose on that day. Fab4 will also blame Nandini for her hiding things and somewhere to Manik too. Manik will lose friends and Nandini. These are two most important things of life of Manik. He will be finished in one way. Aryman will take his revenge by hurting Manik's emotions so badly.

But these are my point of views. Give your opinions too.
