And on this day, the obvious was stated.
When a Rabbit Hole is examined by Wendy, she says, "I'm too big to fit down there" and in RoG, when she examines a collapsed rabbit hole, she says someting like "No one will fall here", so, I think that Abigail is dead falling in a rabbit hole. Excuse for the langage mistakes but English isn't the langage that I speak better
