The only time the Sax parivaar got excited in the last three months was when they got the news of Prat's fake pregnancy. Even that evaporated the minute the entered the SS house and Arushi started her tantrum. These two Sax sisters are notanki ranis. Every time it's some notanki or another.
BTW, I don't remember Krishna every laughing out loud since his intro. episode. He is slowly but surely headed towards the Devdas route since the day he met Prats.
