Mihika would have shocked everyone, especially her love of life, Mihir, to get married to Ashok recently. Though everyone tried to take her away from his clutches assuming he had forced her to do it, Mihika would have silenced everyone saying she married Ashok with consent. Mihir would have been heartbroken and shattered hearing this.
No body would have realised that Mihika was blackmailed by Ashok and Suraj saying they would get Mihir arrested and hanged for attacking Suraj. Also, they would have threatened her about Ruhi's court case and use it to corner her. Mihika, believing Suraj was really in coma after being attacked by Mihir would agree to marry Mihir.
Mihika would have pretended that she married Ashok with consent and that she was happy with the marriage. But her sister, Vandita, who knows her sister so well to know that she is unhappy and that she is pretending to be happy, corners her and brings out the truth out of her.
Let's wait and watch Yeh Hai Mohabbatein to see if Vandita would inform everyone about this and save her from Ashok's clutches or stay silent like Mihika.
