After reading all the articles and topics and after watching the latest promo, I think (and I am also certain) that Arjun won't marry anyone except Poorvi...the thing is that Arjun-Poorvi marriage will not take place now and it will take place after some more time i.e. the marriage will be delayed...but this latest promo suggests that there are a lot of twists, turns and suspense planned for us in Pavitra Rishta...but these twists won't hamper Arvi relationship...yes...it may be that someone else (probably Ovi) would sit with Arjun in the mandap but once Arjun and Archana see that it is not Poorvi with Arjun, then they won't let the marriage happen...instead as usual there will be a big drama in the occasion and arguments and slaps and so on...come on guys, after watching this serial for such a long time, we all are now aware that no PR occasion can be successful without any drama...so there would be a high drama but no Arjun-Ovi marriage..instead we will have a better marriage for ArVi later...😃
