Even if she goes and lives with trilok for sake of suhana
I am ok beacuse jo bhi ho rahi he saamne se ho rahi he
It's not like kzk or ssk where malhar sees her after months living with a stranger that would defo lead to all mu.
Here he knows trilok he knows suhana and probably he will meet them before kalyani beacuse suhana has met him after Boxing and I even feel mlahar would see the look alikes pic too
So there is no chance of mu and malhar is not that foolish to realize that if kalyani tries to try marry or go with the guy it's for pillu. He realised it at rachits time without reason so it won't work.
Surrogacy we can't blame him beacuse usse sara sa bhi bhalank nahi ki sampu was barren after moksh according to him she was Prego so how come he sense and klaayni ka rape story was convincing too as she was unconcious and found in freezer.
So Even if kallu goes to his house none will have an issue as all knows itnwill be for suhana. And kallu will never cross her limit
But sooner or later malhar will sense something wrong about trilok.will try and warm kallu and she won't believe him or will brush him off until she gets trapped
