Samuel

Samuel is a citizen who is briefly seen in Half-Life 2's opening chapter, Point Insertion.

Biography
Samuel had lived in City 14, but the Combine had him transferred to City 17. By coincidence, he was in the train car that the G-Man teleported Gordon Freeman onto. At first, Samuel was mildly startled and stated to Gordon that he had not seen Gordon board the train, but soon brushed it aside and went through the station alongside him and another citizen.

Further into the station, Samuel saw one of Wallace Breen's Breencasts and remarked to the other passenger that he had hoped he had seen the last of Breen in City 14 and the other prisoner warned him not to say that too loudly, as City 17 was Breen's headquarters. It is unknown if he survived his stay in City 17, as he could have been killed in a Civil Protection raid, the rebellion, or when the Citadel melted down.

Trivia
Samuel was originally meant to have an Asian model, but that model was instead used for Laszlo. Additionally, in earlier versions of the game, Samuel was meant to have served a large part in explaining the backstory to Gordon after saving his life by giving him a gas mask (in this version of the game, the Combine was replacing the Earth's atmosphere with a gas that allowed them to survive easily but was deadly to humans).
