Revealing mistake: After Nick escapes from the agents, he runs to a convenience store and bangs on the door for help. While he's doing this, his reflection can be seen on the glass of the door he's trying to open.
Question: Even if David captured Nick, what makes him think that Nick would ever work for him? It's been established that he doesn't have a family and doesn't really have any friends, so it's not like David could threaten him into compliance.
Answer: He didn't need him, just his body to experiment on. If the circumstances could be duplicated, he could create an army of intelligence agents.
