- A reference to the Quentin Tarantino film Pulp Fiction is present when Zoltan asks what happened to Zed. Geralt replies "Zed's dead," referring to when Butch Coolidge (played by Bruce Willis) tells his partner Fabienne what happened to the character Zed from the movie.
- There's a third option to get the John Natalis Card from Ravik that will keep him alive, without playing Gwent. Before approaching the thugs, you can throw a bomb at them and they'll attack you, while Ravik will survive. After you talk, he'll give you the card.
