Hannibal did not choose to sit in the chair that was there for doctors to listen to the woman. He didn't want to do anything that would make her think that what she was saying frightened him in any way. Moving now would only work to distance her, and that wasn't what she needed. She needed somebody that she could rely on.
"I have not heard of it, you are correct." He admitted. There were many things that he'd had to learn in this new place and new time, and he had a feeling that even this city didn't know what it was she had. "I guarantee you that my lab surpasses any standards that you can think of."
It was a boast he did not make lightly. Before the incident with Simon and the monkey, his lab had been incredibly sterile and secure, but after it, he had doubled all of it and made it so that he was the only one who could get in - or out. There were precautions in place that even he thought were mildly ridiculous, but had put in place anyway, thinking of the things that he liked to work on, and the incompetence of regular people.
"I can take your blood and saliva samples myself, transport them by hand to my lab, since it is just upstairs, run the tests myself, and return here within the next twenty minutes at most." He looked at the clock on the wall of the room and then nodded. "I promise to not dally or get too caught up in what I'm looking at. Do you wish to take your own blood, or will you permit me to do that, if I adorn myself with the proper coverings?"
The last was not said with any sarcasm or condescension. He took what the woman was telling him seriously, and would continue to do so until the time when he saw nothing in her bloodwork, which he did not think was going to happen.
"Given what you are telling me, I will not offer to shake your hand at this moment. But I am Doctor Hannibal Lecter. I am the head of diagnostics here, and the head of surgery. If anybody attempts to take over your case while I am out of the room, you direct them to my name, and they should back off very quickly."
