1. Bani knows that Jai may be busy with his meetings or otherwise and wouldnt have the time to save her. Pushkar being unemployed has nothing better to do and could easily come and save her.
2. It was her way of telling pushkar (who was waiting for her) trhat she willnot be able to make it to meet him.
3. She still unconsciously likes Pushkar alsthough consciusly she did tell all of us she loves Jai.
Do you have any more ideas???
