Here is my analysis on the promo
Case 1:
Ektha and her dufford DV's are trying to mislead us by showing this promo. Actually DM is supposed to reveal the real killer name right? and finally they will show that only in real bandini
Case 2:
DM came to know about the real killer name and he is not in the position to give the punishment to that person is like mother to him (Moti)
So he asked Santu to sit on the chair and do the nyay again. Santu is giving the punishment to Moti
Case 3:
Santu came to know abt the culprit and going to reveal it infront of the family members
But i don't want this to happen. i want DM to reveal the killer name. as he became LION again and entered into roaring mode
