I think the biggest twist is the death of the kids resulting in the complete annihaliation of JB and JW declaring all out war on AD & Bani. I think there are already signs of a war between Bani & JW brewing with JW saying he has taken Bani's punishment up to now, but not at the expense of his kids. And all the articles speak of Bani completely destroying Jai. What could destroy him any more than she inadvertently causing the death of his kids.
All the viewers can still see a way back for JB even with the mental asylum track, but most normal people won't see a way back for them if they are blaming each other for their kid's death. But in the illogical world 😡 of KS, they will probably stack up the odds against JB that high, and then bring about a reunion, when we probably won't even want it any more.
PS. Chak De India is slamming good!!👏
