Who is this Vikram?
1. Lawyer?
2. Producer?
3. Lover?
4. Blackmailer?
Vishaka is refering him as "Tum". So he must be a young chap.
She needs to marry him and she needs Shastrji's approval - That is why she is calling it tamasha.
She wants to get it done before Dev and Rad leaves VR because only they could convince Shastriji for her second (first) marriage.
Or Vikram wants hear truth from Dev about Vishaka and Dev relationship. (Dev had promised that he will tel the truth whenever she asks for it)
But this does not answer Vishaka hiding from the police? It looks like both Vi & Vi (one more Jodi?) has involved in some fraudulent business (or loan in the name of Dev's wife) and they need relief from Dev.
But how does it fit in CB theme? This track must add some substance to the story especially RaDev love.
