Well
if Baa/Moti/M-Family say to DM "Santu and Arjan had a fight in regards to accusing Khemi of sleeping with Hiten, and Arjan refused to believe Santu's accusations and went to you to complain that night, and Santu followed then killed Arjan... Santu has admitted all this, and thats why we sent her to Jail. She admitted she wanted Malkin power..." it SHOULD automatically set a warning sign to go of in DM's head because DM knows that
Arjan was accusing Khemi of such things and Santu wasn't even
there when the fight happened. As long as he accepts this in his head, because obviously in that situation DM will first want to find out why Santu lied before proving her innocence.
If that doesn't click in his head, or CV's totally ignore this point then there isn't even 1% of logic remaining in this show. I don't think I'll be able to watch it if that happens.
