Archana is the only one who could set things right - she knew Purvi was hell-bent on getting her and Manav back together no matter what and now after her own life is now in order she is siding with Ovi who actually betrayed the father who raised her for 18 years and a mother who she never knew but was simply a deal to get the guy of her dreams inspite of the fact that the guy admitted in public that he was not willing to marry her.
I dont' understand parents like Archana and Manav - once Arjun said that he was not interested in marrying Ovi they should have made her understand that marrying a man who does not love her is USELESS!
TEJU is the best sister in all of this - she is the only one who knew exactly what was wrong and correctly interpreted everything - in fact if given a chance she might even want to actually see Purvi and Arjun get back together.
I don't think Purvi should go back to the Deshmuks or her aaji's place - she needs to stay away from them all and just tell them that now was not the time that I need you but when I did need you all back then when I was hurt with trying to get back my parents together and sacrificed the man of my dreams for your daughter Ovi I was shunned - now I don't need you all...Archana needs to feel what it means to be loved and lost...for someone who has gone thru much in life she has certainly not understood Purvi at all ...
In fact, Arjun and DK need to set the record straight for the Ds and give them a piece of their mind and if Manav tries to butt in DK needs to be firm this time and tell him YOU SHUT UP FOR ONCE COS ALL THIS TIME I HAVE BEEN LISTENING TO U. Moreover, I think that Manav's attitude to others by raising his hand to silence others is VERY RUDE! He listens only to his mother and adopted son who turned out to be the best villains on the show but was quick to forgive them when actually they had destroyed his family's life...if Soham knew what a villain of a cousin he has in Sachin he would certainly give him a piece of his mind.
