Lol youI talking as if you didnt see the show from start.
Kavya married Kabir becoz of Vyom dying wish only. This topic has been discussed the nth time and you guys still point fingers????? And if you denying all that discussion then nobody can convince you clearly.
And lol its not like Kavya is completely over Vyom. Yabir are not like married couple in true sense. They are still awkward in moments and have a friendship kinda relation.
Its Kabir who gave her this news of Vyom. Remember Kavya trusts Kabir, why would she doubt him about Vyom's truth?
Even for the audience it was shown that Vyom was indeed a double agent. Why should Kavya set to prove Vyom innocent when he clearly is not?
And here we missing the point that Kabir and Kavya friendship was independent of Kavya being married to Vyom. Why should she not believe Kabir?
I mean its Kabir whom we talking about.
I do feel these questions of why kavya married vyom/ believed kabir/ didn't suspect vyom is a double agent have become monotonous. There's nothing hard to believe about it when kavya in the past much before the revelation to her said that she trusts kabir just as much as she trusted vyom, she saw kabir as her and vyom's only family (we need to remember that kavya has known kabir closely for more than 5 years before arush's birth too). Also she even said in one of the earlier episodes that she fulfilled vyom's dying wish (which vyom said in front of kabir-kavya in a FB scene). Also like you pointed out its not like kavya has assumed a normal husband-wife relationship with kabir and still acts like a friend with him and is mostly formal with him, where the few moments where she showed discomfort and slight jealousy at ishaani's attempts at getting close to kabir at normal given kabir is still her husband and she is aware that ishaani has feelings for kabir and family wanted them married. What would be weirder is if kavya just stood there expressionless or without any reaction to ishaani's obvious attempts at getting close to kabir etc irrespective of whether she doesn't have romantic feelings for kabir yet.
