AND THE KILLER IS....
GUNN OR ADITI!
It cannot be Om or Parvathi as they are too adarshvadhi to kill someone, especially their family member. Remember long back when Om thought that he was the one who killed Ajay by mistake, he only told Parvathi to go to court and say that he is the killer. And not only that, if Om's character was to be sent to jail, they wouldn't have reintroduced him into the seriel by showing so much of crap!
It cannot be Kamal, Chayya & her hubby, Vandy mausi as they have already shown them to have some secret which Tanu knows, i.e., a motive to kill Tanu. And in such cases, especially Ekta's seriel, people who are shown explicitly to have motive to kill are often people who are suspected, but in the end it turns out that they are not the killer. They purposely showed these ppl being scared of Tanu whether she will leak out their secret, so that audience suspects either of them to be the killer, not only audience, even ppl like Om & Parvathi. So I don't think either of them will be the killer. And anyways, I don't think they will risk losing the character of Kamal and also the audience wont accept it (remember some time back when they tried to bring in a track where Kamal was negative, audience dint like it and they had to revert the track).
It cannot be Gauri or Shivani as they are themselves so involved in their own problems, and both of them are wondering how did Chotu go to jail, unless maybe Gauri figures out that Tanu was behind this! But I don't think Tanu would have anything to do with Chotu going to jail as at those times she wasn't this spoiled, and not only that, as she said, if she does something, she will do it openly and not like 'some people' who does things behind the back and pretends to have a good face.
There are slight chances that Ashu can be suspected, as he has been acting quite suspicious offlate with regard to Chotu going to jail. Maybe Tanu came to know about it and must have threatened Ashu. But again I think it is quite unlikely that Ashu must have done it, as the only thing he did was send Chotu to jail for a crime he HAS commited, but he falsely did it in Gauri's name! I don't know whether coming out of this secret can motivate a person like Ashu to actually kill someone, especially his family member! And not only that, they have already shown Ashu in a suspicious manner to the audience, so i think it is quite unlikely that Ashu is the culprit!
It cannot be Adi, as again, after Tanu behaved badly to him and he got slapped by Om, people might naturally doubt it is him. So I don't think its him.
Then the only 2 ppl left who are not shown explicitly in suspicion is Gunn & Aditi.
Why Gunn?!
Well, now Gunn is the only one person whom no one will suspect, not family members, not police and not even audience as she is Tanu's mother. What could have been her motive? For the past few weeks, Tanu has been creating lot of problems for Gunn and the family, from the day she started modelling, then when she realised Gunn is not her real mother and that Shruthi is her real mom, then Shruthi brainwashing her, Tanu taking drugs, flirting around with Adi, threatening to go public and spoil the image of Agarwals, lots of things like that. So after seeing all this, Gunn must have realised that Tanu has gone out of their hands and there seemed to be no way to bring her back. So Gunn must have decided that instead of letting Tanu spoil herself and the family, it is better if she is dead! I know it is difficult for a mother to do something like this, but sometimes for the welfare of everyone and thinking wat all miseries Tanu might cause to herself and her family if she is left like this, the mother must have been forced to do something like this which no mother can even think of! And since this is an Ekta Kapoor seriel, these things are possible (remember Tulsi killing her own son Ansh)!
And not only that, Gunn is a very unimportant character in the story. Whether she is there or not, it doesn't affect the story or audience. The only reason y the seriel needed her till now was to bring out the secret of the exchange of kids, and cos she is Tanu's mom! Now that Tanu is not alive and the secret is out, I don't think even if she is not there in the seriel, it will make any difference. So proving her to be the criminal would be the safest bet for the creatives, so that the seriel does not miss out on any important character!
Why Aditi?!
As far as Aditi is concerned, I cant think of any particular motive for her to kill Tanu, but generally in such situations, the motive also comes out only in the end which might shock everyone! Like maybe Aditi liked Adi (Tanu's boy friend), and to get him she must have killed Tanu to dispose her out of her way. Everyone knows Aditi's past, that she has had a troubled childhood with her parents passing away early, so maybe she is a mentally disturbed child and she grew up with lot of insecurities. Then when she came to live with the Agarwarls, she might have been jealous that everyone is concerned about Tanu, she is loved by everyone. So she must have been frustrated that even the guy she liked likes Tanu! Or maybe the reason might have been a simple one that she really loved Parvathi mama a lot and Parvathi loved her family a lot, and Tanu was making their life miserable, so she must have killed Tanu!
The people who are given the least focus in such investigations turns out to be the culprit! So from the above analysis, I think the killer should be either Gunn or Aditi!
Please tell me ur opinions and comments, and whether I have missed out someone ๐ณ.
