Purvi not telling anything what happen to them because she think Arman not give him permission to stay india more ofter this drama how purvi convince them to stay india to know the truth.
Ovi tell the truth to archana or she played the part arjun ask her and get more hate from Arman even they are now believe ovi is nothing doing wrong but she portray what they thought past 20 years.
Arjun get a slap from manav surely if he saying i am just using purvi to get ovi back . But seriously i think he deserve he make not his life hell but make Purvi / Ovi life difficult .
