I dont know if this has been predicted before or not but my prediction of 26 sept is that it might have been a case of hit and run. Karan-the ex boyfriend could have been the person behind wheels who hit Raima but she saw Sonakshi instead. Sonakshi is not speaking up because of one- guilt of witnessing the accident and two- her mom pressing her to keep quiet. Remember Sona once taunted her mom that it was because of you that truth never came out. Or maybe she was a struggling actress hence her mom must have bkackmailed her with their financial conditions. Rohit would hold Sona responsible for a long time unless ex karan speaks up.
Anyways, if this ineed happens, it would be similar to a K drama plot that I once saw. Heroine took the whole blame of a car accident caused by her fiancee just because she was a mahan aatma. The grey hero's wife was killed in the accident and he made the heroine suffer jail term, not to mention the mental torture only to fall in love later on.
Other predictions are welcome...cheers😊
