[h3]White Church Workshop, Upper Cathedral Ward, high above western Yharnam – Ophelia[/h3]
Dietrich raised an eyebrow at Ophelia's mention of the Nightmare being in him rather than on him, and he raised the other eyebrow when she guessed he might have tried the experiments on himself. He seemed quite puzzled yet also mildly intrigued by her theories regarding this strange hint of something supernatural that clung to him, and a small, relieved smile appeared on his face when she confirmed that the others were bound to the Dream as well.
That smile grew strained with another twitch at the corner of his mouth, however, when Ophelia mentioned Gerlinde; a reaction that was surprisingly similar to when she had mentioned Soulkeeper.

“I don't know all the details, as I said,” Dietrich told her, “but I don't [I]think[/I] any experiments have been conducted on me, no. Nor have they on you.”
Taking a deep breath, the First Hunter explained: “Paleblood, which makes Hunters able to bind themselves to the Dream and attain immortality, is a disease. The experiment, as I understand it, was to artificially induce that disease in people and then turn them into Hunters. All the others at the clinic where you awoke were part of the experiment; every last one of them. But not you. I recognized your name instantly when you told me; you are the [I]one[/I] person out of that crowd to actually have Paleblood. You are the real thing. The others... well, the vicar will want to meet them and see the results for himself. If they are truly bound to the Dream, then at least some good came of this tragedy.”
