Behind the scenes

 * The joke, "War does not determine who is right - only who is left." is a quote from Bertrand Russell.
 * His name could be a reference to Tim Curry's Character "Wadsworth The Butler" in the movie Clue. In the movie "Wadsworth" is a rather cynical butler with a distinctive English accent.

Bugs

 * Sometimes Wadsworth will stay in the player's bedroom, or get stuck on the player's bed, preventing the player from entering and using their bed.
 * Sometimes if the player is not aligned with Wadsworth's eyes while getting a haircut, half of players face will be cut off from the screen. Crouching may result in the screen showing the player's pelvic area.
 * When speaking with him, it is possible the focus-changing animation and his movement may result in the PC occupying the same space as him.
 * He sometimes confuses the PC condition phrases: you may enter your home in full health and he advises you to seek medical attention; conversely, he might say, "It's good to see you alive and well" when you're seriously wounded.
