I think Krishna will reveal it to Raghav . Since Raghav and Kirtis video is already taken by press they may release it to news and everyone will come to know tat Raghav and Kirti are brother and sister. Tat may be the reason tat Raghav came to Deshmukh house for dance and all which videos we have seen . His Amma was also
there. I think kirtis engagement also happening . May be during tat sequence something big will happen like Raghav will use Sulochana against Pallavi and all . At last Pallavi will be forced to leave to Kolhapur . May be at tat brim point Krishna will reveal to Raghav tat she was the one who saved ur Amma’s life . Or may be after coming to know tat Raghav and Kirti are bro sis , so to make Raghav understand Pallavi is innocent Krishn may reveal it for his knowledge . Tats wat I guess
