I agree. It should b Real Riddhima....But if she is not i want Real one to return like a phoneix. This girl then can b her long lost twin sister.I think it's Riddhima only and that's why they are intentionally giving hints that it's not Riddhima to create suspense. I mean just one episode and Vansh and all fans doubting her, isn't it too early if she is not Riddhima? But ph can show anything later duplicate or Riddhima. So let's see, but I will go for she is Riddhima theory as of now.
