I think we were discussing this sometime earlier about how Rajeev's diary could have been used for good angst - Ru wondering about the relation between Pree and Rajeev, probably feeling jealous of his dead brother, and then feeling guilty about thinking that way - so much could have been done there. I think I will forever be salty that they didn't explore that track more.
Oh yes...we were discussing this!
I will forever be annoyed they didn't address this! Instead we got excess Yuvraj drama.
This should have been explored during diary track & been part of process of Ru falling for Pree.
Even if not at that time, but when Ru found out during that dope DNA test about Saaransh, there should have been some focus on him thinking that means Pree was never with his bro (I know there's a single line in the episode but it doesn't have that impact) & maybe, how glad he is about not having to share her with his bro.
