My Theory after today’s episode
Aai will alert ragahv n Pallavi in his way without knowing Mandar because doctor said she is fit n fine
1) Pallavi said ragahv to write note n keep ur pocket always with him
2) Keerti or Mandar may try to kill Pallavi in future which can let Pallavi to have memory loss or separation or misunderstanding
3) letter conversation between them if in future Pallavi will have memory loss this letter is going play a role in it
4) Keerti n sunny intentions Ar not good
5) Keerti will have major Downfall in future because of sunny n Mandar she will Realise his mistake
