Trivia

 * The name "Farkas" actually means wolf in Hungarian.
 * There is actually a bug/glitch where Farkas will draw his weapon, and talk to you constanty, as if he was a guard attempting to arrest you. If you try to wait while in the same building, it will say " You cannot wait while guards are coming ", same with Fast Travelling. It could be possible that Farkas is considered a Guard in-Game, and will pursue you untill all your crimes are paid for in gold, or prison sentence.
 * He is Vilkas's twin brother as they were both raised together and their names both mean wolf.
 * During the Companions Quest chain, if you ask him "The Companions are werewolves?" he will respond that only the Circle are werewolves and "It's a secret to everybody", a reference to the well known qoute from The Legend of Zelda series.
