He looked pained. "I assure you we don't do anything here that is remotely like that particular, unfortunate procedure."

She stared at the ceiling trying to grasp what he'd just said. "So how risky do you think this is?" she asked finally. "Truth time."

He looked away again and sighed. There was a long silence in which he seemed to be pondering some extremely troubling thoughts. Finally he turned back.

"In medicine there Is always something that can go wrong. Even the most innocuous procedure can end up being lethal if that's what the gods want that day." He looked at her intently and seemed to try to measure his words. "But I wouldn't recommend we proceed if I didn't feel that the potential benefits far outweigh the risks."

She listened wondering. Something in his voice is sounding cagey. What is he leaving out?

"I still want to think about it"

"Of course, but we can make some preparations in the meantime," Van de Vliet said turning back to Nina. "Mrs. Hampton, do you understand anything of what I've said? Nothing is risk free."

"Young man, if you'd lived as long as I have, and then felt it all slipping away, you'd be willing to take a chance with anything."

"Mrs. Hampton, Alzheimer's is one of the more promising areas of stem cell research. We've already had successes here. I truly think we can help you. In fact, Ellen can start your preliminaries right now, if you like. A lot of it you may have done before. For example, there's a game where you have to memorize the names of three unrelated objects, and you have to count backwards from one hundred by sevens. Finally there's a test where you copy sentences and symbols." He chuckled and there was a warmth but also a distant sadness. "Some days I'm not sure I could even do it all myself. In any case, it's not something you pass or fail. But if we do enter you into the trials, you'll have to stay here for the duration. That's absolutely essential. We'd also like a caregiver to be here with you, as long as it's necessary."

Ally looked at Maria. "Do you think you want to stay here with Mom?"
