Lucas Smith is a character in His Robot Girlfriend.  He is the son of Mike Smith and his deceased wife.  While I was writing His Robot Girlfriend, my son was participating in Jr. ROTC at his high school.  Because of this, I made Lucas a soldier.  Other than that, he bares no real resemblance to my son at all.  In fact, Lucas has a relatively small part to play in the story, so his character isn’t really all that fleshed out.  He doesn’t appear in His Robot Wife at all.
