Sharing what I posted earlier in EDT here for reference.
Three four times in the past those FB scenes were shown in KA to viewers, where Ehsan tells Katha how Viraj's death got scandalized in media with headings 'Earthcon CEO Viraj found dead with cardiac arrest in the bedroom of a prostitute' which also left deep scar on teenager Viaan.
Later Katha searches net, to dig those old articles on Viraj & gets disturbed before 50 years anniversary event, that's how she recognizes Seema's name and face.
Later Viaan tells Katha during Lonavala return trip about Seema briefly, đon how he became judgmental for several years about women that most are 'gold diggers' 'seducers' 'home breakers' who are after rich successful men for luxuries, this is due to Seema's hot affair for her own benefits with his father, which was repeatedly fed into his brain right from when he was just a 12 years boy who saw his father leave them suddenly.đ (that's when Viraj has last fight with Teji & left home never to return alive)
Here Viaan is more affected after knowing both sides truth now, because neither was Seema a cheap woman, nor seducer, nor gold digger, nor was she the main trigger for fights between his mom & dad when they lived together, which Viaan was brain washed wrongly by Teji/Farah & media right from his teenage.
Execution of this revelation episodes could have been much better, if narrative was more from Viaan's POV as a teenager who got embroiled in elders decisions, but not to point or whitewash who is wrong Teji, Viraj or Seema?
