maybe the File contains the share transfer papers (As yash promised Arti that he will gibe back his share to Aakash), And while reading this Aarti feels his sadness of leaving everything. And then she consoles/supports him?
It's just a thought, I want them to leave SM; okay dont throw ur mouse on me, please, keep reading. At this point It is important to leave the house for them, because, from last few episodes, SP and G3 behaved as they have taken Aarya granted (Prashant Case, Punishing Aarya G3 calling yash paap, scolding Ansh etc). So, when they will be far from them they will understand the importance of Aarya, ABOVE ALL, That Fishy- Ishy Will be far from our Yash.
What Say Guys?
