Just something I thought but doesn't make fully sense about battlers mom
Spoiler:
If I recall correctly battler supposed to be 16 at the events when it happened, his lil sister at the future 12 years later talk with the boat captain about the other side of the island as 30 years ago sadly this doesn't match up exactly as this would be 2 years before battler would been born, but maybe he wasn't exact on the year. Could it possible be that Beatrice is battlers mom? And also that she died by giving birth to him?, Well I don't have much to base this on, just some minor hunch or idea that I got after finishing episode 4.
Also sorry if this been taken up before
bit time consuming to read 105 pages
But at least I think it may possible be true as long as the red text is actually the fully truth
we don't know truthfully as it came from an witch :P
