I expect that my most recent Ep 4 theory is very close to the truth, if not spot on. I also expect that (ep 4 spoiler tagged because I saw Jokrono in the thread) Battler will realize his sin and repent for that, perhaps even somewhat forgive Beatrice because he understands her. The latter of this prediction is admittedly based on the knowledge I have about the initial reception of the ending to Umineko, dunno how much that counts as a spoiler.
(ep 5 spoiler just in case, let me know if I don’t need to tag this) I also expect to personally dislike that one character introduced in ep 5 that’s apparently very popular among old time fans.
