in my opinion , its was a sign for zoya that Yash was a cheat hence her jaizz wish to PRoof yash innocent cant be granted as he was cheat indeed!!
now Adi getting hold of this thread is a different thing not linked to zoya's wish...
Adi longs for sincerity , faith & trust in love. This must be his unspoken wish & he getting hold of zoya's thread is , its zoya in his luck who will give him the sincere love which he always has longed for,
what do you guys think ?
