LOL yes it was baffling to see that why those words came out thats why somewhat apprehensive to see this behavior. She was easily influenced when Daadu mentioned about the faulty vest deal despite knowing from the post lockdown episodes that their fathers are great friends no matter how much big the difference was. Yeah, she was grieving over her father & its understandable to losing your parent but she and shravan knew of their great friendship and even made attempts to reunite em. He thought she will understand it because both of em have even tried their level best to reunite devraj & vijay & when they resumed the friendship during lunch time they were happy that their plan worked. He doesn't know that BB was responsible for burning the bridges so he will react accordingly to.
Shravan basically was expecting that just like they've always been a team and understood BOTH their fathers, the same will be the case this time as well.
From the very beginning of the story, the one thing they've both agreed upon even when they otherwise bickered was that their fathers are genuine friends who care for each other.....so that is all he meant when he said, "Hum toh sach jaante hain na".....he was saying ki the whole world is trying to claim that my father could do this but you know our dads were genuine friends, right? I don't see why him expecting just that much is being labeled such a blunder.
Sumo's thought process was shown in a very jumbled manner and frankly lacked conviction in justifying what she said. Even if she had heard a snippet about Devraj making the faulty vests, the extent to which she talked crap about Shravan, his dad, civilians in general was way overboard. She sounded like Daddu ka mouthpiece.
It would've been better to see her question about whether devraj was primarily responsible or not, maybe she wouldn't have bought up the army vs civilian debate back in yesterdays talk. Daadu be bola ki faulty vest deal wasn't sent than vijay wouldve been alive. So, I feel she's quick to jump to conclusions at times hence somewhat reckless.
