Another episode 8: Gotta admit, when i started watching it and saw that guy was coming, who isn't in the OP or ED and therefore not a main character, i just knew he was gonna die. He might as well have been wearing a red shirt.

The thing the guy left in the classroom:

 Spoiler

It's most probably the desk. Mei explained in an earlier episode that she doesn't know why that desk is there, she believed it was just there to complete the counter-measure charm. Perhaps the desk is the way to determine who is the dead person.

I think that right now it's possible that the "Curse" is sentient. It didn't do anything the whole day, until they started talking about how to fight it, it then suddenly murders someone.

Interestingly, the only 2 survivors (that we've seen) of the incident 15 years ago both have memory blanks and fits of amnesia, and possibly something even more serious (judging by the actions of Reiko in earlier episodes). Perhaps ending the incident early causes it's own problems.

Show of hands; who went "oh pomegranate" the very moment the boat showed up round the corner?
