I really really hope she does leave, that too without telling him, once she makes a profit. It could be for different reasons, though. Like her baba telling her to leave once he finds out the truth about the store's losses, not bothering to find out about the challenge and about her making a profit finally.
Raghav can show up at her house with the intention of announcing that her time is up and then find out she was asked to leave or left of her own accord. Then he will appear at Krishna's doorstep or ask Keerthi where she is. Wouldn't it be so cool, though if she ends up living with Keerthi and Amma for a bit as she has no place to go. It would drive him nuts - the three special women in his life under one roof. Usko to raat ko neend bhi nahin aayegi.
So, if I know Pallavi, who keeps her self-respect above everything, she would never just go away without telling. Even if Baba comes to know the truth and asks her to leave, then too, she will handover her profit to Raghav, win the challenge, and inform him that she is leaving the city for reasons known to herself.
She would not choose to go anywhere but her own home in Kolhapur. Infact, just to keep her close to him and in Hyderabad, he would offer her to work for him instead, since he knows how much self-respect matters to her. Design sarees for his business, since she is so good at that. But mujhko lagta nahi Pallavi ko uske family se dur rakhenge. Let's see.
