In this task, you're given passages that contain mentions of names of people, places, or things. Some of these mentions refer to the same person, place, or thing. Your job is to write questions that evaluate one's understanding of such references. Good questions are expected to link pronouns (she, her, him, his, their, etc.) or other mentions to people, places, or things to which they may refer. Do not ask questions that can be answered correctly without understanding the paragraph or having multiple answers. Avoid questions that do not link phrases referring to the same entity. For each of your questions, the answer should be one or more phrases in the paragraph, and it should be unambiguous.
Q: Passage: Seconds is a mystery dealing with the obsession with eternal youth and a mysterious organization which gives people a second chance in life.
Arthur Hamilton is a middle-aged man whose life has lost purpose. He has achieved success, but finds it unfulfilling.  His love for his wife has dwindled and he seldom sees his only child.  Through a friend, Charlie, whom he thought was dead, Hamilton is approached by a secret organization, known simply as the "Company", which offers him a new life.
Hamilton arrives at a meat-packing plant for a meeting.  He is given workman overalls and hat, then exits the facility by a different door and is seated inside a truck that takes him to another building.  He disappears into a large complex filled with dark, empty hallways, where he awaits his transformation. The Company gives Hamilton the body of a young man through plastic surgery, and a new identity, namely "Antiochus 'Tony' Wilson".  He later discovers this identity has been taken from someone who recently died.
A:
What is the last name of the person who thought his friend was dead?
