Cal eyed the man across the table. "Who are you, then?"

The man smiled, his eyes crinkling. Genuine amusement. "Wouldn't you like to know!"

"Yeah, I would, actually," replied Cal.

"I've been many people," he said. Regret, sadness.

Cal pressed, curious. "Oh, done something bad, have you?"

Pain. "Haven't we all?"

"The FBI thinks you're a serial killer. Are you?" Cal asked outright.

"I'm not your man, Dr. Lightman," 'Adam Pierson' replied. Truth, but...

"You know who it is, though, don't you?"

"If I did, it wouldn't do you any good." A hint of anger, but also amusement. Gotcha.

"He's dead, isn't he?"
