Who is the mastermind?

I strongly believe it is Devyani, cus she shows no symptoms of virus even thou see is exposed. And when she was with PM and PM told her to go away or else she will be exposed too, she sais it so casually, that she is already exposed.

Noo...

All clues as of now point to Devyani Bhaumik. Looks like Dhruv was her Partner because instead of confronting Dhruv she said that people in the Hotel are now exposed to the virus. She also saw her fathers suit being compromised, yet she did not speak a word. She may be against him because of his behavior with her while she was dating Dhruv and because he is helping the PM. Also, She does not seem to be exposed to the virus despite of being with Aditya but her father is affected by the virus. If he was the mastermind, he would have already used the antidote on himself so that he is not affected by the virus. Apart from that, because of her closeness with Aditya she also has the ATU activities update.

On second thoughts, since the villain is mostly someone you least suspect, it could be Pritvi as well. He knows that he is the second in command and if Adi is out of the way he will be the PM. He has information on all activities of ATU as ATU Head updates PM of the progress of the case. Despite of having the memory chip he kept it with him as he knows that she can be a thorn in his path. He wanted to meet Adi first because he wanted to influence him before Naina meets him. So I won't be surprised if he turns out to be the real culprit.

50% I feel that Devyani is the mastermind bcz somewhere I feel that she is the only who killed Dhruv in the ATU and she saw that her dad's suit pipe was broken yet she dint do anything . And other 50% I feel is Dr Bhaumik bcz he is a businessman and the antidote of virus can make him the god of ppl and more richie rich (like how they show it in movies) . And sometime I feel that both father-daughter duo are the masterminds .

I kept a poll on Twitter n Devyani is winning lol

No 1: had Devyani killed Dhruv or did sumthbg, Dr sunny who entered after her wud hv noticed that but she didnt said anything

No 2: how can Devyani see the hole in pipe from so far...too much to digest

These 2 points makes me think otherwise
Making Devyani culprit wud not be so interesting as per me

Dekhte hai who turns out to be villain

Dunno why, but i so feel its Devyani Bhaumick who could be the culprit in all of this. Her character has been multi-shaded thru' the show, she's had a bad track record..not that her past makes her automatically bad, she could've changed too..but in this case, even in a lot of present situations she's been acting fishy. Giving all of us a reason to doubt her..

I was thinking about Prithvi till last episode . Because from antara suicide epi he seems fishy . But one point is very important as someone mentioned here . Why devyani not showing symptoms ? In today's epi precap she is giving tablets to adi also as a doctor . Plus her blood was tested for drug result & they still haven't declared the result of it . I think that antidote will be found in her blood also , & it will be the trump card of makers & they will only show it in the last epi .
