Beatrix Russell is a gun-for-hire, currently employed by the doctors of the Followers of the Apocalypse. In her long life, she's experienced a lot of human nature, and finds that "physical and mental anguish are especially exciting to explore".
She enjoys drinking, which is ironic since the Followers at the Fort work to help addicts recover from drugs and alcohol. Partly because the Followers won't allow her to drink, she finds her job at the Fort a bit dull.
One of the pieces of advice she will give you is the quote "Time you enjoy wasting isn't wasted time." This quote was said by Bertrand Russell, a British author, mathematician, & philosopher of a similar name.
Another piece of advice Beatrix offers is: "The only thing I know for certain is that I don't know nothing." This is an adaptation from Socrates, another philosopher, "One thing only I know, and that is that I know nothing."
Another piece of advice she will give you is "Good...bad...the guy with the gun makes the rules." This is a reference to something the character Ash says in the movie, Army of Darkness: "Good...bad...I'm the guy with the gun!"
