Just watched the new promo

I just watched the new mahashivratri ka mahasaptah where tai confess that she tried to kill her mom n survi n karthik have tears in his eyes n says mang kar toh dekhti yai aapko sab kuch de deta n she says thik phir de apni jaan ki kurbaani n she throws snake on him n he falls down n survi shouts karthikk and tai laughs
I think karthik will be saved or survi will save him but what would be karthik's reaction to it? Any guesses?
