If it was any other character - Neha, Simmi or even Sharon - the show might have proceeded. But it's KRIYA!!! It's the one character that lives inside every girl; it's the epitome of sweetness, resilience and innocence - of stubbornness, strength and a fiercely driven work ethic/determination to dance. It's the girl that's already been shown to fall wildly, madly, passionately in love with Rey...
And it's just DUMB how they can simply replace someone who's in love with another CHARACTER altogether! Because no matter what anyone says about "first love" and "last love", the truth is that you ONLY love once, your soulmate, your heartfelt asset, your true other half. I don't believe in shows like DMG, that show a girl falling in love twice and a guy falling in love with a second, completely new girl. That's crap.
In simple words, the show MUST go on - but it canNOT go on for many of us without Shakti. She and Amar are the essence of D3, blossoming with matchless chemistry. If you think you can recreate this couple, then you're wrong.
They can only be recreated in paradise!
