Survis dupatta ' Karthiks Suspect

Survi's dupatta - Karthik's Suspect

I wonder if Survi's dupatta was left behind when she was locked in the store room.Because if Tai shows the dupatta to Karthik or Karthik sees the dupatta, he will suspect Survi because:

remember just before Karthik left Survi to look for Aniket, his bracelet tangled with Survi's dupatta and she tore her dupatta to free it form the bracelet. A piece of the cloth was left in Karthik's bracelet. He can match the torn dupatta to that piece and suspect Survi.

But Karthik is a tube light, he is the last one to know anything...

And the cuts to Survi's hand from her bangles when Tai grabbed her hand, I hope she has a good explanation for it the next day.

But for now I think Sakhi's ID is safe.
