From Protector of the Grey House:
“What is it that would determine her susceptibility?”
“Whether or not she trusts the vampire. Perhaps we should test the theory if she is willing?”
“If she is willing.”
“Who?”
“You, Mierka, Anthony, myself. When she’s up to it. Maybe two or three weeks from now.”
“Do you think it’s wise to use Anthony?”
“We need to use someone we trust whom she wouldn’t want to possess her.”
“As you wish.”
