No Vasu will be fine in the next episode.
Here is whats most likely to happen ----- Aalekh will go rushing to find out from Sadhna why she signed the papers. Sadhna now assumes that Aalekh and Mallika have feelings for each other (by misunderstanding the letter Mallika showed Sadhna, in which our genius Aalekh didn't address it to Sadhna). So Sadhna will let Aalekh know that she did it of her own accord without any pressure to release him from their relationship. So it will be, the divorce papers will be signed by Aalekh.
Now in all this, I really feel sorry for Mallika. She is falling head over heels in love with this man and will never forgive him. She will be heartbroken for sure and might actually be aid the reunion of Saalekh. This remains to be seen.
My opinion ---- CTs must really look to differentiate themselves with good story telling and real pain. In this track all the pain is self inflicted and no one seems to talk to anyone. Why couldn't Ranvir just let Sadhna know that Aalekh has gone to meet her and wants her back in her life. Is stupid surprise ke chakkar main 4400volt ka Shock lag gaya bechari ko.
