So I have been wondering if the purpose of the CVs is to make Mauli realize the what if?' that had arisen in her mind around the time of the camp track. She had met the person she loved with all her heart after 6 long years, found out what a doting father he was and the romantic in her felt weak and started thinking what if she had not let Kunal go.See, Mauli never had any closure.One day she knew her husband was madly in love with her,the next day she realized he not only did not love her, he was cheating on her with her best friend and on top of that when Kunal returned and made her feel that had he known about Mishti he really would have stuck around, her self-doubt resurfaced. Maybe this track is to show her how she and Kunal have never really been psychologically compatible but could not see it because they were physically very compatible and emotionally very comfortable with each other. Or maybe this track is to show her that this was how difficult her life would have been had Kunal not left her and stayed with her as she was pregnant: she would feel suffocated in her own home and life.
Although it makes a lot less sense, the CVs could have also introduced this plot to make Kunal realize something. This realization is definitely not realization of his love for Mauli. This realization could be the realization of how much pain he had given Mauli when he withdrew from her because although he is in denial, at some level he must be feeling her withdrawal right now. However, this does not seem like a strong point for me because once he gets his memory back, his feelings for Mauli and Nandini would return to what it was and he may acknowledge the pain he has caused her, which he anyways does, he won't feel her pain because he won't be craving for her love and facing rejection. But what is confusing to me is why then, was Kunal not comfortable with the idea of Mauli getting married to Ishaan for just one episode right before he got shot? It would be so lame if they showed his sudden realization of love for Mauli because he literally did not care whether she lived or died all these years and now just because she happens to be within his radar, his hormones are playing up on him? If they wanted to show he was falling in love with Mauli again, that would also be awkward because the CVs showed nothing of the sort. That random scene from that random episode does not make sense to me.
