This episode reveals more information about the participants, giving a better understanding of their backgrounds and possible motives. There was a particular line during the fourth stage that caught my attention. I'm not sure if it was intentional or just a mistake in writing, but if it turns out to be the latter, It would be a major flaw on the story. Based on the investigation so far, I have narrowed down two possible suspects. However, they feel almost too obvious, which makes me wonder if they are simply being used as a distraction or a deliberate red herring for the story. The next episode is the finale, and I really hope it ends better than the previous case because that one almost drove me crazy.
