Replaying Umineko to see how many hints we were given before discovering the "culprit"

I'll do a post after finishing an EP with all the hints that are presented in said EP, starting from EP 1.

Hint: anything related to the true nature of >! Yasuda and the Rokkenjima's incident !<

Rules:

  1. I must present only hints from the said episode. I can connect those to previouses EPs hints but I cannot connect a hint to something belonging to an EP I haven't played yet.
  2. I shall play the VN from the POV of someone that has not played Umineko yet, because with too much knowledge everything can be considered a clue. My benefit of hindsight will be as low as possible.
