1) To whom was Battler's sin against? What was it?
- If Kinzo, abandoning the Ushiromiya family. However, "Beatrice" says that that's not it (EP4).
- If Kyrie, refusing to acknowledge her as a mother, thus breaking her heart.
- If Jessica... breaking her heart despite being a cousin?? I doubt it.
- If Shannon, he could've broken her heart by abandoning her for six years. Battler's vague recollections show that he had a huge crush on her... was it mutual? (EP3, beach)
2) What can we assume "Beatrice" knows and did?
- Wrote letters under the pen name "Maria" detailing scenarios that were never acted out (EP1 and EP2 were detailed in EP3 as the witch's doing).
- Dressed up as Beatrice in front of Maria, Kyrie and Genji (EP2), and Battler (EP4).
- Wrote a page in Maria's diary with magic circles.
- Sent bank account cards complete with PIN numbers (07151129).
- Has the money to set up the high-security vault accounts.
- Knows that George likes Shannon and that Jessica likes Kanon. (EP4, headship challenges)
- In summary,
familiar with Kinzo's occult studies, has enough money to set up high security vault accounts with lots of cash, able to dress up as Beatrice, and is an insider on the love scoop.
3) Who is physically capable of these things?
- Occult: Probably all residents/regulars of the mansion, more likely Kinzo's trusted servants.
Edit: Oh, yeah, I guess Nanjo isn't out of the question.
- Money: All adults, and also the servants. Recall that it is said that most servants could serve for three years and do what they want with the accumulated money for quite some time. Also, the servants occasionally leave the island.
- Imitate Beatrice: The females.
- Knows of the love stories: I'm guessing Shannon, Jessica, maybe Battler, maybe George, maybe Kumasawa.
4) Therefore, who is "Beatrice"? Is it one person? More?
- Based on my analysis, assuming it's one person,
Shannon would be the culprit because she fits all of the "Beatrice" criteria.
- If there had to be an accomplice, I would bet on Genji, Kanon, Jessica, and Kumasawa.
5) When Battler met "Beatrice" in EP4, was it actually a human, or is this an illusionary presentation? Did she seek to reward him for apologizing for his sin?
- I'll bet on "yes" and "no", respectively. But why am I betting? I want to get the right answer!
6) Is "Beatrice" necessarily alive at the end of Eps 1-4?
- Who knows. I wonder if "Beatrice" even cares if she's alive in the end.
7) Can we assume "Beatrice" is always the culprit/mastermind for Eps 1-4?
- Yes. Then again, I can assume anything I want.
8) Is it possible that "Beatrice" is not the culprit in Ep5?
- Very much so. The magic circle(s?) is extremely shoddy this time around, and the twilights weren't even finished. Someone totally half-assed it, and still got away with making Natsuhi the culprit (assuming she's innocent).
- Now that I think about it,
isn't it strange that an envelope with Kinzo's ring inside it IS SEALED WITH KINZO'S RING????
9) Is the "offended" seeking revenge? Or could it possibly be a favor for the intended survivor? If not, what exactly? Did the sin merely cause a chain reaction, like a series of dominos?
- I'm not sure, but the EP5 hints suggest that it is love-driven.
