I think Mr. Dubey might tell Yash if Aarti doesn't agree to the Bone Marrow Transfer because he'd have no options left. If Aarti refuses, he has to figure out another way to get Ansh in the operating room for Prashant. He'd have no other choice but to tell Yash about it! Until now, he's only been scared that Yash will say no to the transfer, but since it's a do or die situation if Aarti refuses, he'll have to take the risk.
And I don't blame him. He just wants his son's life and so does Shobha. A parent would kill for their child's life, so what the Dubey's are doing is nothing out of the ordinary.
If you had to be angry at someone, you should be angry at Aarti. Not the Dubey's. Yes, the Dubey's are begging them for Ansh's bone marrow, but she's the one who is keeping it from Yash. The Dubey's haven't taped her mouth and tied her up. She has a voice, she sleeps in the same room as Yash. She's had SO many opportunities to let it out, yet she hasn't. If anyone is to blame for this situation it's Aarti. Instead of saying "The Dubey's are selfish", shouldn't we be saying "Aarti is selfish"? Doesn't Yash have the right to know Aarti's truth from Aarti herself? Why should the Dubey's care about what happens between them? They won't get affected once the truth comes out, but Aarti will. She isn't telling Yash, but I don't see any "Aarti's selfish", "I hate Aarti", "Aarti is horrible *angry*" posts on the forum. Many of you identify with her circumstances and aren't criticizing her. Then why can't you identify with the Dubey's?
Sorry, I just had to let that out.
