"At this point I do not know if you and everything that has happened in the last three weeks are merely figments of my imagination. I can only work with hypotheticals and what I do know.

"I have not gotten sick from breathing them in. Miss Ellie would have killed me herself if she did not agree. The only thing that is 'bulletin board-worthy' is a great big sign not to enter the museum so that nobody will panic about what is inside, but a sign like that will only encourage people to come and investigate for themselves. She has suffered more than anyone should ever have to suffer, and I will not put her through killing people here."
