Episode 5 ends the anime original chapter, the Yakusamashi-hen. Just to note this chapter was supposed to fill in the minor details that were left out in the first season. And not to mention build up upon Rika's real role in all of this.
[spoiler]Overall, this episode ended with EVERYONE dead. Though a few points to consider:
- Who exactly are those mysterious men, and who sent them?
- Why does it have to be Rika that have to get killed?
- The gas incident did happen yet Satoko was able to escape from it by falling off the rope bridge. Sounds familiar? It should!
- Rena knows something as Satoko dreamt her final actions before getting killed by those same mysterious guys.
- Nurses are evil!
Satoko dies from a "heart attack"....yeah right![/spoiler]
Next episode starts the Minagoroshi-hen which is part of the Answer arc which "answers" the Tatarigoroshi-hen (episodes 9-13 of Season 1) which also serves to answer a lot of the other lingering questions presented before.
