good post.
You are right, that both Aditi n Varad have something on their minds, esp Varad. Now the 'vaaris' order from NA/Anjali. Dunno if he was around when the pest came to stay in agni mansion. I remember now, the stove wala scene n varad was arnd, but soon after he disapp n the pest was getting calls on her ph from mystery person (varad?).
Maybe swati is insane n varad knows n went to see her, aditi is taking revenge on her behalf. Hence she knows all info about family n swati stuff.
Both hvg pumpkin shaped vases maybe a coincidence. But nice observation by you.
