1) when u kill, u should get the job done quick asap and get out of there...not loiter around chatting with the victim, passing badass dialogues to a supposedly about-to-be corpse
2) wear a mask or hood...dont get out of the car showing off ur beautiful face for possible witnesses to glimpse or even to the victim...tying hair is a must with hood on, as even a hair can risk police knowing ur presence on the crime scene...as the cop found out about arjun with his hair in season 1
3) dispose off the clothes u wore if they have blood stains on them...burning is best way...do NOT sit around in an UNLOCKED bathroom scrubbing and washing them...and also never leave ur own bloody shoe prints all over in the house leading possible witnesses to follow them and come see u! like VM did.
4) wear gloves...do NOT touch the victim all over leaving fingerprints
5) NEVER confess even in front of a sleeping person in a whisper...for even walls have ears...like jahnvi heard everything! what she was doing who knows? poised to just appear as soon as maya finishes confessing...does jahnvi suffer from insomnia too? like daughter, like mother
6) Make sure the victim is dead before leaving the spot...so u dont have to have the risk of finding out he is still alive and in a hospital!
7) Also, maya sat there. Going through the camera and deleting the tape...instead just to be safer and quicker...grab the camera and delete it later...
8) Get a carwash. The car left all bloody tyre prints...and im sure even the car must have got some stains or marks on it...
9) As shown in previous episodes, maya's car always has a kerosene can handy 😆 so best way to ensure ayan is dead would have been pouring it on him and set him ablaze...
10) And last but not the least, double check if u left any possible evidence behind before scarpering off...
