but the letter surely says that the poison was for bani. so i doubt it is sent by someone other than tarun. the leter reached rano also is sent by someone else not tarun. so can be sahil escaped from tarun's clutch by faking his death. since rashi is gone to london she will be back with full energy...
altogether ur assumption and krishna's too is possibilities... let t hem do whatever want with jail or seperation... why the hell this tarun and bani marriage... for God Sake... are these people are blind or duff...
