I now have a new theory 😆
Chandrachur/his family or maybeeee Thakuma will shoot Kaka/Kaki killing them, and wounding Tapur's leg (as seen in the BTS video of the wound on her leg). Then court scene post leap makes sense too. 😕
Or Kaka/Kaki's death will be for some other reasons but nothing dramatic. However, Tapur does have a gunshot wound on her leg. Maybe this is TM's doing, because she's furious at Kaka.
Ani will find out, and won't tell Bondita because maybe Sumati Ma asks him to keep it from her, or some circumstances will lead to it. So that she focuses on her studies, and won't be trapped in guilt.
Then Ani will go back to India to take care of the issue (maybe help take care of Tapur/Tupur/Sumati Ma) and lives there in guilt, while Bondita stays in Salim's guardianship.
I'm feeling like he'll definitely take her to London, but will return to India and won't come back to see her after that. It's also possible that Bon herself tells him to go back to India.
