From The Grey House:
“We met when she saved my life.” He continued the story from there, being as thorough as Vincent asked. He wanted to avoid telling him too much but had no choice but to tell Vincent Natalia’s story as well. There was an uncomfortable moment when he told his boss about biting her to make Natalia his permanently.
“She kicked you out of her life for that?”
“She saw it as a betrayal.”
Vincent nodded. “Was that the last time you saw her?”
“No. We said goodbye after she found out she wasn’t a werewolf.” He looked away from Vincent’s steady gaze.
