And in yesterday's episode i.e., January 4th episode. Rupali was saying something to either Amit or Carol (I forgot who exactly) that Ravi has suddenly started calling Carol sister... dont know what has gotten into him... and she said, he has suddenly started doing this for 3 days...
This means that he started doing it from 1st of January... it makes 3 days until 3rd and they telecast the episode on the 4th...
And Guess what... Ravi talked to his wife on the 31st... Do you think, his wife asked him to stay away from Carol?
