A sad ending, but a good story arc. It's sad to see so many side characters fall to the Akuma, but it was definitely in the back of my mind that all the humans had to have been affected by the Akuma with that level of exposure. Linalee's innocence evolving to protect her as it did has yet to be explained, though the Bookman seems to think it might be significant since it's never been done before. Is Linalee the heart? Is Allen? Who could be the heart?
