Bronson Jarls's CGI rendering uses Sentinel Grunt textures for his shirt and pants, a different face texture with a headset, and a blue helmet that has a slightly different shape from the standard Knights Helmet worn by Bronson in-game. The CGI rendering used for the Mission Tracker uses his correct in-game textures, but still uses the different blue helmet.
Occasionally, a glitch might occur in which Bronson Jarls's gear is removed, revealing his white hair tied back in a ponytail.
Bronson Jarls's quote about chewing bubblegum is a reference to the movie They Live.
