KalMa's relationship will take a lot of time to progress. Let's not forget how their relationship started. It is only now that they are on equal footing with each other. It is only now that both of them are trying in this marriage. And I can't say that they don't trust each other at all. It is more along the lines that they are not understanding each other. Kalyani is not understanding Malhar's feelings for her, and to some extent, I don't blame her. Because Malhar, up till the Athrav marriage track, has not done much for her. Now that he has realized what a good person she is, and he is fallen in love with her, he wants to be a good husband to her. But she is not used to this new Malhar yet. Kalyani is operating the way she usually does. In her life, her son and mother are the first priority, not Malhar. Up till now, this was not a problem for Malhar because Kalyani was not the first priority for him as well. Kalyani has not yet realized how much Malhar has changed, how deep his feelings are for her. The equation has changed, and KalMa need to realize that.
Also, that security guard, I am pretty sure he is Sampada's father and Madhuri's brother. I think he may have a positive influence on Aparna and Sampada similar to how Appa did on AS.
