In the dinner scene, was the uncle's wife having a seizure as a result of being shocked of Su-mi acting out as Eun-joo or was she possessed by a possibly demonic spirit since she saw the dead girl's ghost beneath the sink? Also, I've noticed that the movement she made with her hands matched the movement of the hands of Su-yeon, Su-mi's younger sister, when was crushed by the closet and the wife also made choking noises which probably adds on to this.
shareDepends on your interpretation. Most people think she was possessed.
But I think she was just having a seizure probably triggered by Su-Mi.
The sitiuation was VERY tense at the moment.
And also it seems to happened more than once as the husband ran away to get some medicine for her. Why would he possess pills against seizure if this was the first time? So I say no ghost was involved.
As for the ghost under the sink, it was just hallucination from her, I read people who have seizure can hallucinate things.
