- when maulik saw hiten on phone he wonders who arjan is with. ( he might have gone to verify but not shown)
- It is shown some kind of movement of DM while he was laying on the floor.
- Arjan lifted the bat to hit DM again and Santu enters and she is shocked but it was not anywhere shown that what actually Santu saw. Did she see Arjan going to hit DM or Arjan already killed and DM laying beside or something else!!!!
- After Santu opens the door she is shocked and nothing was shown, everything happened in closed door.
I think:
Either Maulik has killed Arjan in advance or DM got little consciousness, killed Arjan while protecting himself or may be Santu and lost it again.
