They know generation leaps most of the time don't work. Especially if the show is already having bad times, going for generation leap won't gain them anything. Even more if everything is dark after it like Saanvi being bandhua. I don't know why are we scared of this generation leap.
Keith stint in Udaan won't be over any time soon because he said he will be one of leads, he is "long stay' character and as for now nothing hinted that. More over, Karan still doesn't have real enemy with Sukor. His only motive is stealing idol and works with Imli because of that. What I think that most probably will happen is he will try to put blame on Chakor but Chakor will turn the cards in her favour. That means she will just be saved, or she will reveal his truth and made him arrested. But this man has already confessed his responsibility for death of many people by that bridgefalling and got free next morning. He won't get convicted so easily. He will be back very soon and will have real motive to become Sukor's enemy.
Imli... she will probably be discovered but not so soon. Most probably Sukor will have some doubts after Kashmir but won't know about her. Maybe they will blame Karan for everything but also know some women worked with him. Once Karan is in jail, Imli will lose support so it will be hard for her to influence Sukor.
If she is reveled after Kashmir track... I don't know how will that work. She still doesn't have any pover but it's possible the will be protected by Karan. And then more planning and plotting but now with Sukor knowing about her, still that's not interesting there is no twist or anything. I don't like imagining about her as much as I don't like watching her, so I don't have any idea.
I don't see why Sukor will get separated. The only separation that could happen between them is death and that is most unlikely to happen. They could have fights like recent one over Chakor becoming project menager, but that doesn't need to mean and shouldn't include separation.
