I think that right from the beginning Banis life wasnt in any danger😉. Even when that house was burnt with Bani in it, the policeman said that no1 was trying to kill Bani only frighten her. Bani gets a call everytime abt the Park street raaz and then some1 frightens her so as to instigate her to ask Jai abt the raaz. I doubt thats a real time bomb in todays episode . Roshini or some1 has set it up so that one of them (Bani mayb)will assume that she is dying and force Jai to tell her the truth. When the truth is out Jai will realize it was jus a setup, and Bani mayb too angry with Jai.
In todays episode it looks like some1 is either after jais life or Banis life. Think abt it who the hell will wanto murder Jai for tat accident tat too 7 yrs ago? Banis dad is the only one who wud want revenge and he is dead. Why murder Bani at all? Mayb by killin Bani, Jai wud b single again. But for Bani to leave Jai all tat any1 has to do is to make her err stumble on the truth or even even better make Jai confess. Which is wat is happenin Killin Sandy means no witness to rat on Roshini😛 I think Roshini mayb behind it.
