8. Pasamalar scene to hint the audience on sentimentality of the character, which would invariably feel the pain (even the enacted ones) of the other as his own. A sobbing mother and a helpless, sad father in front of him, he is definite to feel their pain and behave the way he did.
9. His tiffs with the constable, growing enmity and also to infuse suspicion when he stops doing that post the incident
