Without Raghav, it doesn't feel like the show it started out to be - from a sweet blossoming love in Austria to god knows what - this show has really changed so much!
Anyway, here's my two cents. I have a feeling that Raghav is in on Dadi and Naina's plan - I mean I can't imagine that Dadi and Naina have moved on with life and are making such elaborate plans if they thought Raghav was dead - They didn't mourn him or even show any remorse or sadness ...If they truly are unaware of what happened to Raghav, they cannot just put it aside and set out making plans..Naina will surely want answers and try to find Raghav, unless he's already surfaced as we'll see in a flash back and made this plan together with dadi and naina.
I guess the two months that Naina lived with Ahana, she would have learned a lot about Ahana's life and her in-laws and is now using that to pretend to be Ahana's ghost ..I think this will make harjeet confess her sins and Rehan will get to know the truth about his mother ..
Perhaps then Raghav will return - and they will explain the whole thing to rehaan ..In the course of this, Naina will realize that rehaan is actually a good man and she will think that the baby rightfully belongs to him ..
Rehaan will then leave with the baby back to Austria - so the title "pardes mein hai mera dil" will make sense as the baby is the dil of both naina and raghav in some sense ..right now the "pardes" aspect is totally forgotten ..
naina and raghav will get together and finally live happily ever after ..and if the show is going to end ..that's how perhaps it will ..or then if not, CVs will continue with their drama ..or leap with the baby grown up and more and more MUs and what not!! ..
I just hope that we start getting a lot of Raina soon ...Audience will forget raina and start being okay with naina+rehaan if they continue this track for too long!!
Let me know what you guys think? I haven't been watching the shows ..only reading updates so I might be totally wrong in my prediction!!
