The next day, the two remaining women were told that Denise had to leave early due to a family emergency. Siya and Regine carried on with a d ay full of yoga and mindfulness practice. After dinner they went back to their rooms. Unknown to them, Siya was to be offered to the Spirit of Earth that night.
The plan was to pump in sleeping gas into her room after she fell asleep (they cannot kill her with carbon monoxide as she was supposed to be killed by 'Earth'). Her unconscious body would then be brought to the ritual where she will be buried alive.
Things got complicated when the sleeping gas vent broke down and Siya was thus fully awake when Ani, the cultist tasked with bringing her back entered her room. In his panic, he accidentally strangled Siya until she stopped breathing and went limp. He realized the shit he was in as he wasn't suppose to kill her. So Anil frantically gave Siya CPR until she was successfully resuscitated and then he quickly chloroformed her unconscious again.
Only then was she brought to the preparation chamber where Dr Rajeev dressed her in her red (symbolizing Earth) sacrificial costume, made up her face and then wrote the mystical symbols on her belly, just like he did for Denise the night before.
Siya was then buried in the sacrifice pit for 2 hours before her body was dug out for Mr Pritchaporn to enjoy. She was then left to rot in the pi, awaiting the 4th night where her body would be used again.
