Satya goes blah, blah,blah...and then "Abh confusion katam hogayi lekin mein ne abhi bhi thumhara trust nahi jeetha"... That is what made Antara to go with him. She was reluctant, she had tried saying she will wait for MM but Satya kept on his blabbering but when he started about trust and all, as a pure soul Antara didn't want him to feel bad. He is anyway DM's son, who had recently told her that they will start fresh. How could she make Satya feel bad ? If we see that scene again it is the crap's insistence and her unaware of Satya's true colours which made Antara accept the lift. She still sees Satya as a part of Raghu's family. Raghu you need to tell her the truth otherwise she is in big trouble.
