"You are at a . . . tricky stage of your recovery. Cryo-revival amnesics seldom recover all of their memories at once. It comes in little cascades. A typical bell-curve. A few at first, then a growing mass. Then it trails off. A few last holes may linger for years. Since you had no other gross cranial injuries, my prognosis is that you will eventually recover your whole personality. But."

A most sinister but. He stared at her beseechingly.

"At this stage, on the verge of cascading, a cryo-amnesic can be so hungry for identity, he'll pick up a mistaken one, and start assembling evidence to support it. It can take weeks or months to get it straightened out again. In your case, for special reasons, I think this is not only more than usually possible, it could be more than usually difficult to detangle again. I have to be very, very careful not to suggest anything to you that I am not absolutely certain about. And it's hard, because I'm theorizing in my head probably just as urgently as you are. I have to be sure that anything you give me really comes from you, and is not a reflection of some suggestion on my part."

"Oh." He sagged back in bed, horribly disappointed.

"There is a possible short-cut," she added.

He surged back up again. "Wha'? Gimme!"

"There is a drug called fast-penta. One of its derivatives is a psychiatric sedative, but its usual use is as an interrogation drug. It's actually a misnomer to call it a truth serum, though laymen insist on doing so."

"I . . . know fas'pent'." His brows drew down. He knew something important about fast-penta. What was it?

"It has some extremely relaxing effects, and sometimes, in cryo-revival patients, it can trigger memory cascades."

"Ah!"

"However, it can also be embarrassing. Under its influence people will happily talk about whatever crosses their minds, even their most intimate and private thoughts. Good medical ethics requires me to warn you about that. Also, some people are allergic to the drug."

"Where'd . . . you learn . . . goo' med'cal ethics?" he asked curiously.

Strangely, she flinched. "Escobar," she said, and eyed him.

"Where we now?"

"I'd rather not say, just yet."

"How could that contam'nate m' mem'ry?" he demanded indignantly.

"I can tell you soon, I think," she soothed. "Soon."

"Mm," he growled.

She pulled a little white packet from her coat pocket, opened it, and peeled off a plastic-backed dot. "Hold out your arm." He obeyed, and she pressed the dot against the underside of his forearm. "Patch test," she explained. "Because of what I theorize about your line of work, I think you have a higher than normal chance of allergy. Artificially-induced allergy."

She peeled the dot away again—it prickled—and gazed closely at his arm. A pink spot appeared. She frowned at it. "Does that itch?" she asked suspiciously.
