Tapasya is marrying Rathod which means that she is cutting herself off completely from veer's life. But without Veecha and Tapasya any no.of Rathods will not make Uttaran a story. Since the link of (so called) love (which in reality is obsession) will be definitely severed now with the marriage now its time for HATRED saga. This Saga is taking roots with this tapu veer confrontations. Tapasya is bitter that she has been cornered and only way left for her now is to marry Rathod which actually means she failed. So in order to prove herself that she is a PRIZE ( as Rathod loves her for herself) and that Veer is wrong in always degrading her she had made this trip but unfortunately for her Veer as usual has different POV in this. So the blame game starts. Logically Veer shud atleast protest this and shud give her a good setdown instead of going on a guilt trip. Only this will make Tapasya to hate Veer the way she thought she loved him...
Since Veecha will be reuniting very soon...May be Tapasya will kidnap Ichcha's baby and bring her up hating their parents thus this hatred saga continues to the next generation...just my guess.
