scenario 1:
Both ovi and purvi vl be pregnant vth arjun child vth an execuse that he did it vth in a drunken state or she planned it in that way with the stupid idea of punni... and in case of purvi its frm d cottage scene... then during delivery ovi's baby may die.. then ovi may replace purvi's baby with her dead baby vth punni's help (where both deliverd on same day in same hosptl)...
then after some roona doona of purvi for her baby where all becum soft cornerd for her pain... then punni vl eventually blackmail ovi for money and someone like sulo or archana mite find it out as punni's family mite return back to karanjkar's house.. then whole plot gets exposed and arjun hates, yells at ovi and return back to his love along with their baby... and every one would support it as ovi has given purvi alot of pain and atlast for d baby sake as the baby need to get the love of both the parents...
scenario 2:
ovi mite get to know purvi is pregnant and b4 anyone cud know abt it she vl ask her to leave the city & she plans a gud drama of making arjun drink fully and create in frnt of him that they had a relation but actually it would not b their... then she mite get pregnant thru surrogacy with someone else sperm... and punni would help her in it.. then it turn out that the who actually donated the sperm actually loves ovi alot and did it for her happiness(just as our arjun married ovi for purvi's sake) and eventually the truth mite be exposed by someone like punni herself or the person or the grt detective team in d serial like teju (just as she did in archana's case) and this would lead to arvi reunion and end up ovi marrying that sperm donor & who loves her...
sry guys if i hav hurt anyone but even this could even be possible if she wants to reunite arvi ... as it is ekta's show... thought of posting it... do comment...
