I dont get it Shikar said that Mayuri killed Gayatri, because he admitted that to her, and he wasnt lying then because no one was around. So Shikar is not lying, and if Mayuri didnt do it then who did. I have a strange theory, here me out guys. This murder happened ten years ago, that means adi/chotu was also about roughly ten. What if adi comes and sees gayatri strangling mayuri and stabs gayatri. it is possible one of the reasons he is also affected by the knives. Guys did that video actually show Mayuri stabbing action, i think it did so I think mayuri did kill gayatri, but in anger witnessed by adi.
yeah i think my latter theory makes more sense. but if the former happened then adi could be in emotional turmoil and yes we can expect some MADI romance.
