With what the Bomoh said, it then hit me.
Kurnawan pointing at the nose, Hazidah going for cosmetic surgery for her Andy.
Lastly, with Andy's weird obsession wanting her to look like his ex-girlfriend that died.
There was only one possibility.
The bone used for her nose in the cosmetic surgery belonged to Andy's ex-girlfriend.
This guy is simply just obsessed with his ex-girlfriend.
So obsessed that he dug out his ex-girlfriend's grave and used her bones to put inside Hazidah.
That piece of shit!
Should have gutted him at the bus stop.
Having known the answer now, I kept quiet.
Choosing not to tell anyone of what I'd figured out.
Sometimes the truth is best hidden, does no one any good to know other than letting them live in regret and anguish for the rest of their life.
