I remembered that Pallavi talked about someone’s death just before her wedding to Mandar once. That was when Raghav shared his past. She then brushed off the story saying it was raghav’s turn to talk about past pains. Then again while drinking with amma she mentioned her best friend who died.
My gut feeling is that Mandar had always been a psycho and obssesed with Pallavi. Her friend might have found something about him before wedding n Mandar could have killed her. And him being out on his wedding night might be related to that. I get this creepy scarry feeling whenever thst ‘tum mere ho’ track plays and he looks to crazy who would just go ‘p...p..pallavi’ and write her name on his chest with knife like srk in darr. Yikes 🤮🤮
