about the new promo

I dont think survi is the doll. In that promo survi is devastated and went to temple. There only she is meeting the doll. That means the doll is that person who knew the truth of tai and like survi.
Possibilities are
1 kishore who is not dead yet
2 shanti, one of ma frnd here told her thoery being shanti may be the doll
3 sreekanth.. i dont knw the reason y i think so, but i feel it!!!!
