So Hans is saved, if the spoiler is right.
This would be better. I mean there is no way anyone other than Hans and her mom knows about what all she did. So if Purab gets to know it, and then brings in the swap it would be good.
Anyways the swap wouldn't work like last time, coz Purab now has the instinctual *feels* of Taps while doing rituals. So in a way if he continues with the ritual, it would mean he is agreeable. Still Taps doing it without his knowledgeable is wrong.
