"Well, first i ought to apologize to Vincent, that I was unable to prevent his fall. I was up on the scaffolding with him and lost my balance as well."
Then, returning to the doctor:
"But what I meant to talk with you about, and I didn't want to bother everyone, but when he came here he was covered in an unusual substance. You wouldn't have had it sent for analysis as well? I was going to collect some myself, but Vincent's well-being came first.", he said eagerly.
If this was something paranormal, it was an opportunity of a lifetime. True, Roger had seen his share of unexplainable cases, but he'd actually witnessed this one. He wanted something tangible to put in his file. The audio tape had proved less than satisfying in that regard.
Of course it would probably be better for the theater if that substance mysteriously disappeared, both from the hospital and from the theater's attic. Even if it wasn't a haunting, he couldn't imagine a substance like that being present in their attic bringing any positive reviews.
