Jessica's astma attack and everyone calming down. Cant spend more than couple of hours a day to this. Damn it'll take forever
Anywho. Few more thoughts.
Kinzo's dissapearance is played as a great mystery. Natsuhi is accused of lying about meeting Grandfather. However.
We clearly see from Natsuhi's POV that grandfather is deffinetly there when she went to the study for the first time with Genji's key.
This is pretty much one of those things I asked about wether Umineko is like Higurashi's episode 1 or more like episode 2. Wether I can even trust what is presented to me as "this stuff happened"
Thus since it's shown from a characters point of view I asume it must be true. Even in higurashi when Keichi "sees stuff" the people are actually still there. It's just a little.... distorted.
So I refuse to think that I witnessed an event with Natsuhi talking to an empty space for five minutes. even Higurashi didnt do stuff like that.
Thus. I see Natsuhi clearly talking to Kinzo the first time the study is opened. He is there.
However:
1. I only have Natsuhi's and Eva's word for it that he wasn't there the second time. They just return to everyone and say "Granpa not there". For all I know Natsuhi and Eva said "Hi, father! Everything's fine and dandy in the mansion. Ok cya! (dramatic exxageration, but you get the point)
2. Eva's almighty "clue". Unless I massivly missunderstand something I only have Eva's word for it that she ever even placed the damn paper in the door in the first place. From Natsuhi's surprised look she had no idea about it, neither did anyone else. Sure, maybe Kinzo wasn't in the study, so Eva thinks: "Hm, white a nice idea to mess with everyone's heads" Creating a compelling doubt against Natsuhi, where there is none. I'm surprised Battler ate up that clue so easily considering how much he turns over chessboards.
