And I guess... That..
1- Radhe is not the real culprit... The scenes may be included to confuse us...nothing else...
2- the mystery man in the precap may have come to prove Pankaj as the culprit...
3- the mystery man may leave some doubting proofs against Pankaj to make Yuvraj change his decision...Yuvraj may change his mind after those fake proofs... . As the CVs won't show such simple story line of husband supporting his wife...
4- I haven't seen the promo yet...But I believe the background voice may be of Yuvraj... At the time of witness... He may change his statement... He may go against Pankaj after having those proofs..
5- the point where Yuvraj goes against Pankaj... There w'll see separation between Yuvani...
