Karva Chauth has been shown in Kasturi already so I wonder if that's going to happen in kayamath as well.
It should be fun to see the three married couples, all unhappy for various reasons, winging their way through this ceremony.
Prachi, the pati varatha, will surely keep a strict fast. Suyesha has already said she'll never keep one (don't blame her either..tho' she might keep one for either Mickey Mouse or Whiskey!). As for Ayesha, she'll probably hog her way through every morsel in the house..and that too in plain sight!
No guesses for which of the husbands will secretly keep a fast for his wife!!
