[Because I have nothing better to do with my life, have a list of various headcanon things I've filled in for Murphy's history. This is more of a reference for myself than anything else, but I just thought it'd be cool to share. Bah.]
Heather Mason: Murphy Pendleton... How do I begin to explain Murphy Pendleton?
Annie Cresta: Murphy Pendleton is flawless.
Chase: I hear his mustache's insured for $10,000.
Topher Brink: I hear he does car commercials... in Silent Hill.
Tate Langdon: His favorite movie is Reservoir Dogs.
Harry Dresden: One time he met James Sunderland on a plane...
John Tillman: - And he told him he was pretty.
Alex Shepherd: One time he punched me in the face... it was awesome.
