DK?
Yaar i diligently watched Mannat for 50 episodes in the beginning. didnt like much so watched only ayesha's clips. Then got back during aman's track thinking it will be revelation. Then could not watch more than 10 episodes. I watched clips though. So I am not sure of DK.
But post leap I am following closely. I am more interested now only in analyzing how they are screwing up all the good chances of turning the story into right direction. Even now I am more interested in mannat uncovering the truths. More that vik. Because I think she will just accept him. More interesting will be when Dk become a real conflict in mannat's mind. Till now she doesnt know his feelings. Once she knows, and seeing how mannat is written, she will have HUGE conflict. It will get into "lost" zone where a lot of questions on morality will come into picture. Dk either has to die or free mannat off any guilt by marrying another woman. But dont worry I dont think writers will take it to that level. They cant handle it. They will just kill DK saving Dua.
I also hope DK to die rather than turn evil because Mannat will break again for believing a wrong person. DK might have to apologize may be for unknowingly ebbing mannat into lying...if they give his character that much importance. I am leaning towards DK's death.
Haan pre-leap episodes, show how being a cop he got Blackmailed, committed crimes , was the reason ARS was out of the jail, EB Mannat into lying to Vikrant.
All the trust he shows now, watch how he treated Mannat pre-leap until he met Dadi and found out the truth & how Dadi died. He infact finds Mannat hurt and locked in a trunk, Vikrant traumatized because of Vish and Malla, he still goes on to support Vish, Malla and threatens Mannat. He even supports Vish taking all the Saluja wealth to Mannat.
So, brushing all these under the rug and trying to show him as a goody too shoes is too hard to watch. He is no different than Malla or Y for me, atleast they are shown as criminals.
Edit - also don't miss the wedding episodes, the same guy who is shown to be defending Mannat, silently watches Vish CA her and Vikrant's outburst on Mannat. Not once does he even try to step in to reveal he EB Mannat into lying.
Let me ask you, what do you perceive of this scene alone? Ignore the caption on the X post.
. They have very good understanding...thats all. I didnt watch preleap much so whatever is shown post leap, DK seems good to me. 
, he already felt his line was clear when he confirmed with Mannat if she knew about Y in Indore. Now he has further opportunity to showcase his greatness, and claim rights on Dua and Mannat which he did in today's episode. Surprisingly, Since pre-leap his loyalty and attachment only lies with Mannat though Vikrant was his brother.
